There’s nothing stopping you from using open source drivers, actually. Plenty of open-source projects like Dokan will typically run fine with an anti-cheat (ours will, certainly). What stops you from running a patched version is actually Windows itself, since Windows requires drivers to be signed with an authenticode codesigning certificate. Plenty of open-source projects and people have one, though. So it’s not an anti-cheat blocking you, it’s Windows itself. Of course, if you go out of your way to disable driver signature enforcement, most anti-cheats will prevent you from playing, but this is a mode strongly discouraged from Microsoft and does weaken your computer’s security.

If anti-cheat is the thing that cares about whether windows is running without driver signature enforcement then anti-cheat is the thing that's blocking me.

My own example: I have an xbox 360 dancemat, which is unusable with the official drivers (they map the arrows as axes, so treat left + right as nothing). So I have to use the open-source XBCD, which frankly I'd treat as more reputable and better code quality than most signed drivers. But since no-one's paying the $100+/year to sign it, it's not signed. And while I understand why Microsoft wants someone to have skin in the game before they issue a driver signing certificate, they really need to find a way to ensure that reputable, established open-source driver projects get signed if they want users to accept driver signing; I wouldn't even mind being stuck on an old "certified" version or something.

I sympathize with you and wish it was possible to support your situation and those similar situations like yours. It’s just disabling signature enforcement effectively removes a key security boundary between kernel and user space, something that that would just be too easy for cheats to exploit.
