Minisforum AI X1 Pro 370 BIOS Unlock

[linkhyrule5]

Something of a long shot, but -- anyone know if there's a way to unlock the BIOS on the Minisforum AI X1 Pro 370? I've downloaded (and flashed) the 1.06 BIOS (which I believe is the latest), and tried unpacking it/working with it myself with ifrextractor and UEFITool, but mostly what I've found are bad signs -- the updater just calls afuefix64.efi /capsule, for example, so at least the 'official' route involves a signed ROM. I have essentially zero experience with UEFI fiddling, though, so I'm hoping I'm just ignorant and there's a workaround I couldn't find on my own. Ideally one that doesn't involve physically connecting to the BIOS chip -- in principle I wouldn't mind trying, but I can't even find the BIOS chip, I think it's on the back of the motherboard which would be a serious pain to access...
