Can confirm. Upgraded last night on Brix Pro 4770R. Upgraded Clover. Copied kexts over to 10.12 folder. Added HFS efi as suggested by HeadKaze. Downloaded and upgraded macOS. Had to select boot macOS install on reboot in clover. 20 minutes to reboot. Select boot macOS in Clover. 15 minutes to finish install. Log in. Seems to work so far.
