Secure boot and let the game attest the boot state.

It would restrict you to a series of whitelisted kernels, probably from major distributions, but it's better than the current situation.

that sounds like a reasonable compromise, it may even provide more control and protection over what they are able to achieve on Windows?

i remember their anti cheat was utter crap tbh, not like something that Riot implemented for Valorant (a kernel-level system that runs from boot-up with deep system access)
