"... the detectability of this patch is practically non-existent. That is, unless the anti-cheat system deploys its own EFI application to check for the patch or attempts to load an unsigned image. By the time the OS boots up (more specifically, after the call to ExitBootServices - which occurs long before any boot-time Windows driver is loaded) the DXE driver will already have been erased from memory."
If you are using this to bypass anti-cheats I have a very bad news because anti-cheats are now dumping SPI flash to validate BIOS images.
