but how can you prevent the user from modifying the kernel?

You can't, but circumventing anti cheats already happens on windows with all their fancy kernel level anti cheats.

I believe the goal is to make it so uncomfortable and painful that 99.999% of the users will say fuck it and they won't do it. In this case users need to boot a custom kernel that they download from the internet which might contain key-loggers and other nasty things. It is not just download a script and execute it.

For cheat developers, instead, this implies doing the modifications to allow those sys-calls to fly under the radar while keeping the system bootable and usable. This might not be trivial.
