lanzarote - solutions have already been suggested, and they would work, but here is some more detail on what you asked, in the hopes that it creates clarity.
If you want your bars up 2 to 3 inches while keeping the bars the same distance from you as they are now, you will need to change a lot.
The stock stem on this bike is set at -7 degrees and is 90 or 100mm depending on frame size.
So assuming your bike size comes with a stock 90mm stem, you would need to swap the stock stem out for a 35 degree stem that is 140mm long, and remove 20mm of spacers. I havent seen a 35deg stem that long, but maybe it exists. This is what is required to get your bars up 3 inches and also have the handlebars set at the exact same position forward(reach) as they are now.
A more realistic option- cheaper, likely more readily available, and also likely more what you need if you need the bars to be as high as you say- just get a 110mm long 35deg stem and install it.
Your bars will be 2.8" higher than they are now and also .8" closer to you. So the bars will be higher up but also closer. That is typically what someone wants when a current setup has them too stretched out. Bring the bars not only up, but also back closer to the rider.
Some context for those here, like me, who dont just automatically know what an 'Alpenchallenge' looks like.
