You can reprogram individual keys if you need to in Linux, so even if your preferred layout doesn’t exist, you can get what you want working.
I personally use Dvorak, and it hasn’t really been an issue. That’s pretty mainstream though, so YMMV.
Regardless, I’ve never even considered Linux support for a keyboard. Some parts may not work, like maybe RGB or macro software, but if you don’t need that, the basic keyboard should be absolutely fine and you can tune from there with standard Linux layout tweak tools. If your keyboard supports QMK, I think that works on Linux so you can go wild with that if you like.
