The great thing about the GRX 46/30T is it is cheap (I paid $150) and is a drop-in replacement for what you have now. The front derailleur needs to come out about 3mm more (H limit screw), so if you can do that, you should be safe. It also helps to be able to lower it a couple of mm, but if you are already at 46T on the large chainring, there is probably no need to do that.
