Downtube index shifters. Do they exist? 10 speed
rear 10 speed indexed downtube shifters to go with deore or tiagra 10 derailleurs, anyone know where to find?

Good luck 10s Mt and Tiagra aren't 10s road compatible

its a gravel bike so i guess the deore 10 derailleur will have to do; you think i can get a 40 on there or 36 tooth?
at the moment i have some wierd shimano 7 speed index downtube shifter, was hoping i didn't have to do new wiring for a replacement shifter and could just drop a 10 speed index downtube, maybe i can go indexless to avoid rewiring (i hear indexless doesn't get caught between gears so much when there's 9 or more speeds).

i hate to have front downtube shifter and rear click shifter but at the price i was wondering if anyone knows about the sram x5 trigger (10 speed shifter) and why is it that some people say it requires sram derailleur? does the direct cable actuation no longer have direct effect on the gear pull on shimano derailleurs, but instead has some kind of auxillary actuation to a mechanism that controls primary actuation of the derailleur?

Here is the long and short of it…
Shimano and Microshift make make 10 speed downtube shifters that are compatible with Shimano road rear derailleurs. They are not compatible with 10 speed mountain, (will work with 9 or less), or Tiagra 4700 rear derailleurs.
SRAM is a competitor of Shimano, so is Campagnolo. They want to sell their own components so they don’t work with Shimano.
You have so many other “potential” issues going from 7 speed to 10 speed on an inexpensive bike, that if you move forward you may end up spending many times more than the bike.
Enjoy what you have and just ride it.

On the surface, bikes are simple, and they work and go together the same way, but, as they say, the devil is in the details. Bikes have gone through a lot of specialization in the last 15 years or so, especially when it comes to the drivetrain, and you can't just mix and match like you could 30 years ago.
A bargain price, "Big Box Store" bike like your Kent is built with the most basic components (that will still function) but they are barely compatible with the things you'd find on even a mid-line TREK, for example. In order to get the 10 speeds you want, you're going to need the shifter, a 10-sp compatible derailleur, a 10-sp cassette, and a cassette rear wheel, because the 7-sp freewheel on your bike won't support 10-sp. Ironically, the "wire" (actually the shift cable) might be the only part you could re-use..
The question is whether a bodged together "upgrade" that exceeds the original purchase price of the bike is worthwhile, or just look for another bike (maybe used) that has what you're looking for.

I'm gonna try to be nice, because it's apparent how much you don't know what you don't know yet, but there's more than just changing the shifter to get "more speeds"

You initially asked about a Kent Nazz for $240. Not that you actually bought it. But you specifically stated in this thread you have a Kent Roadtech from a few years ago that cost $124. Then you ask about placing discs on the disc brake.
The one thing I ask, if you want to troll don’t be stupid enough to name a bike that never came with disc brakes. At least take the 30 seconds to get your story somewhat straight. It’s not fun anymore.

This is what I hate about most people who troll. Sooner or later they just can’t keep on top of it. I had such high hopes for you, but sadly you are no better than the thousands that have come and gone before you.

and, besides, I’m offshore again, so I need something to do to keep myself entertained.

It's a Kent - ride the crap out of it until it dies and buy a better bike

It would be MOST HELPFUL if by 'ten-speed' you refer to 2x5 or 1x10 - or for those that are advocating 10+-speed... There are still many of us 2x-3x front derailleur guys around.
Me personally, I have two 2x6 and two 3x6 road bikes, and even two 3x7 MTBs. But then again, I'm a caveman Luddite....

I would do 10 speed friction. Why would you want indexed when friction works so much better? You can go high to low with a single throw. Also no compatibility worries as long as your derailleur will travel far enough.

And as long as your downtube shift lever can pull enough cable. What downtube shift levers, indexed or otherwise, can do this?

I feel like other older styles would work as well. I have 9 speed Dura Ace indexed on a Lemond. I have also swapped out my 83 Miyata 610 to 9 speed 700c which worked fine with the stock friction downtube shifters. I have since switched to 8 speed mega range however for lower gearing. I can run the full range high to low with one throw and half a pedal revolution. Very handy when rolling to a stop sign. I have switched to friction on a couple bikes when I got tired with constantly fooling with adjusting something with indexed shifters
Indexed is great if you need the smoothest and fastest shifts possible. The only time I would need that is if I was racing someone up a hill. Otherwise, I much prefer the simplicity of friction

Campy 10s Indexed
Shimano 10s indexed with some friction in the front.
