That really depends if your motherboard with its current firmware version has unlocked nvram. 99% of Z170 and above motherboards do not. Which is why EmuVariable.efi is required and uses nvram.plist in the root of your ESP. You can test to see if your motherboard nvram is unlocked by make a copy of EmuVariable.efi in EFI>Clover>drivers64UEFI and nvram.plist to your Desktop and remove them from their current location and then open Terminal and type:
Code:
sudo nvram TestVar=HelloWorld
Reboot and then open Terminal again and type:
If you see HelloWorld in the output that means that you have native working nvram and can remove EmuVariable.efi and nvram.plist from your system. If you do not see the text in the output then you will need to continue using those.
