More likely is that some linux distro like SteamOS gets a large enough install base that it actually makes sense as a target and these big platforms make their anti-cheat work on at least that distro. As unfortunate as it is not having a very strong anti-cheat or a system like Valve's VAC ban to detect and lock cheaters out leads to really shitty online experiences in public lobbies for PVP games.
Some anti cheat works with proton if the game dev allows it. But anti cheats are generally not effective on Linux because you can just load your cheat as a kernel driver.
What kind of device & kernels driver attestation is possible in linux at the present time?
Secure boot, signed drivers, attestation, is all possible. But you can just sign your own driver anyway so kinda useless.
Might be possible with a more secure mode that is booted into when you launch a game that only allow specific drivers and programs like the game and maybe discord.
