For drivers, I don’t think so. You can enable some boot settings that allow you to run unsigned drivers, for development purposes, but it will revert upon reboot, without anyway to enable it permanently.

You just have to disable Secure Boot in UEFI first. (And I can confirm Windows 11 doesn't actually require Secure Boot to boot, I've had it off for months as part of win11 certification testing.)I'm not sure but DRM might revert to lower levels (e.g.: 720p), but that also happens on macOS when you disable SIP IIRC.

It’s the reason that game cheat makers look for exploits in random drivers to load their cheat in kernel space.
Also, updates will probably revert the changes too.
