Got mine to work on an ultra small itx case (RGeek L65) with a pico PSU. Had the brilliant idea to look into under-volting as the pico psi couldn't keep up under stress tests and would reboot the computer due to the power sucking i9 9900K.

Good news guys! I've managed to boot with F12 bios. It is easier than you think. Here is a simple step by step guide.

1. Make a boot USB flash drive with your current EFI folder.
2. Download bootx64.efi and copy it to EFI/Boot/.
This is some kind of alternative bootloader that starts with the command line. Here we will modify hidden BIOS settings.

3. Update BIOS to F12 (only F12!)
4. Reboot and hold F12 to boot from your USB Flash drive. Now you should see this command line.
5. Now enter
Code:
setup_var 0x5A4 0x0
Code:
setup_var 0x507 0x1
Reboot from your primary drive. You Hack should boot normally. But don't forget to set up your BIOS settings.

:!: Looks like we will need to do this every time after trigger «Reset to default settings» option in BIOS.

P.S. If you are interested in the details:

0x5A4 is CFG Lock option in BIOS
0x507 is System Time and Alarm Source option

This codes are not static and can be changed in future updates. You can use this guide to find this code for future versions of BIOS.
Thank you! These offsets are the same for F12 of Gigabyte Z370 Aorus Gaming 5 ! It works like a charm :)

Just wanted to say there is a new .F13 BIOS file for the GA-Z370N-WIFI available - the adresses for CFG Lock and System Time and Alarm Source stayed the same as in .F12, so b166ar's procedure is still valid for .F13

I only tested the System Time and Alarm Source option on my system though.

Sorry, in advance, for my newbie questions:
I'm just looking for a little guidance on your post:
1. What format is the bootable USB Flash drive
2. When you say "reboot from your primary drive" I assume you mean your MacOS drive?
