New update: I used https://github.com/Mattiwatti/EfiGuard's Loader (modified a little bit for compatibility with PowerMonkey) with PowerMonkey (used -90 CPU Cache + CPU Core + -40 GT Uncore and GT Unslice), and it works without Secure Boot + S3 sleep.
Used https://github.com/Mattiwatti/EfiGuard/issues/2#issuecomment-478998015 to add UEFI entry for Loader.
