At that point you might as well not have a kernel level anti cheat and companies who insist on kernel level anti cheat will block wine. The only solutions I see are
Developers mainly use server side anti cheat
They make native Linux games
Distros provide a way to ensure a untainted (signed) kernel
You cannot realistically make it impossible to detect that you’re running on wine. Wine just implements the Windows ABIs. The actual code running is totally different. Even just reading any of the binary code of literally any function would reveal it’s different from the Windows code. How are you going to stop it from doing memory reads on stuff that it needs to be able to read? You can’t. You’d need a full hardware emulator for that.

That would ba a massive win in my book, kernel level anticheat is malware.
make it so that they can’t block wine without blocking windows and kernel level anticheat is gone
