While I cannot dispute the fact that you probably should use a different engine if you want a game to work on Linux, Steam has been working on Proton, which is like WINE, allowing Windows games to work on Linux. I have run my Acknex games with WINE, and they were also whitelisted for use with Proton by Valve.

Whether this means they will work with Steamdeck is a different issue I guess.
