Beelink (and probably others) mini-PCs seem to not bother setting the UUID, resulting in all having the same generic UUID. This causes a problem for Omni, which relies on UUID for identifying nodes.
This will update all American Megatrends (AMI) BIOS to set the UUID to a random value.
Copy all files to a bootable USB stick and boot the mini-PC off it
Tested to work on Beelink U59 Pro and Mini S12 Pro
Use at your own risk.
Originally obtained from inside m1ujt73usa.zip for the Lenovo ThinkStation P330 Tiny download center. The /efi/boot/startup.nsh was modified to run the UUID randomize command instead of the BIOS flash.
