I installed linux mint to a secondary hard drive, then I installed steam onto that Linux install. I play wars two, so I added Guild Wars two as a non-steam game to steam.
I didn’t want to re-buy Guild wars two with steam because I’d lose all of my progress. Once I added it as a non-steam game I just right clicked on the game within steam and changed the compatibility to the newest proton. (I didn’t choose a hot fix version of proton) It runs just fine.
This is what I would suggest that you do , is install it to a secondary drive to see if that variation of Linux will work for you.
You don’t have to change the bios, but when you boot up, you’ll get a boot loader screen that allows you to choose which OS you want.
