You guys do realize that some Linux distros do support secure boot out of the box and there are official tools to add secure boot support for distros that don't. I'm running Ubuntu with secure boot on since it supports it out of the box, the only thing I had to do was add the NVIDIA driver keys to the secure boot keys after updating them so the system would recognize them as legit and that was mostly automated on Ubuntu with me only having to select the correct key sequence and nothing else.
I also don't like being forced to use that buggy over priced, over bloated mess called windows anymore because they have been known to damage parts with updates and their kernel level **bleep** allowed over a billion computers worldwide to stop functioning because of the crowdstrike app. I'm tired of all the Windows bugs, the Microsoft bloat being forced down my throat, and I don't want to risk my pc being damaged in god knows what way with the next major windows update. I don't think what OP is asking is that difficult to just add Linux support for the anti cheat, also just because Secure boot and TPM are on doesn't mean cheaters haven't found a way around them since we can still see these hackers in every game even with kernel anti cheats. There's no such thing as the perfect security so programmers will always find a way to create cheats that circumvent security especially since they earn money through it.
I never head to select anykey on Linux it was always automatically all this keys
