I recently took out my main SSD and installed Linux Mint on a second SSD, which required me to enable secure boot and enroll a MOK key so the Nvidia drivers would work. Later, I switched back to Windows and read that messing with secure boot keys could potentially get you banned in games that use anti-cheat systems. I want to ensure that the MOK key is deleted, but I'm unsure how to do this. Is the MOK key stored on my motherboard? Do I need to reinstall Linux to remove the key, or can I just reset the factory keys in BIOS? What's the best way to handle this?

Honestly, I've never heard of anyone getting banned just for having a MOK key. I think the real concern is just keeping secure boot enabled how your games want it. If you're really concerned, though, you could reinstall Linux, boot into it, and use the enrollment tool to delete keys. But resetting the factory keys in BIOS should work fine too.
I saw someone mention that they got banned because of MOK keys as well, but I can't find solid info on that either! My thoughts are that maybe that user had some other issues. For your case, BIOS reset should remove the keys, so either way, you might be safe to just do that.
I've read that anti-cheat systems on Windows mainly check for secure boot, and MOK keys are just a means to enable it for Linux drivers. I don’t think they pose a risk in themselves. But if you're worried, you could go into your BIOS settings and reset to factory keys, which should remove any custom MOK keys you've enrolled. I think that will do the trick! If you're not sure, it can't hurt to check the options in BIOS.
