I’m not an expert in firmware development, but could a person potentially modify the firmware to bypass anti-cheat software? For say, could you change your hardware specifications or serial number?
Kind of. I’ve edited ovmf firmware to play some games which check for specific strings (for a VM in my case). Anti cheats usually dont care about your firmware outside of that, they care more about your hardware serials (hdd, graphics card, etc)
I’m also no expert but I know enough to know any bypass efforts will eventually result in your account getting banned anyway.
Even if you are not cheating it’s normally against most anti-cheats TOS to bypass their services while in game and modern anti-cheat software is constantly being updated to lookout for that.
