From both a technical perspective and if the maintainers of these anti-cheat will consider porting or re-writing kernel level anti-cheat to work on linux, is it possible? Do you think that the maintainers of kernel level anti-cheat will be adamant in not doing it, or that the kernel even supports it or will support it. I think that if it ever happens, there will be a influx of people moving to linux, or abandoning their duelboots, and that alot of people will hate that such a thing is available on linux.
Yes, but with a modified Kernel you can fake what the anticheat reads when it checks the key, so you just feed it the key it wants to see instead of your own.
The anticheat module would need run on a higher level then the Kernel itself to prevent that, for example alongside the CPU (like the Intel Management Engine).
