Gigabyte X570 Aorus Master Rev 1.1 F33a - BIOS "Windows Boot Manager" problem

[ODuffer]

I'm having issues with the BIOS losing or wiping the UEFI Entry for "Windows Boot Manager"
it goes from correctly listing my SSD (Samsung 860 EVO 500GB) to saying
"no boot device found". CSM is disabled. All the disks have GPT partitions,
there is a usual EFI system partition on the Samsung, and P2 is the O/S - Windows 10.

Here it is working

This has happened twice at random now with F33a.

Has anybody else had this? Any thoughts on why it might be happening,
or preventing at happening. I've basically re-installed windows each time it happen,
a right pain.

Thanks,
Duffer

Useful link that, thanks. I'm going to drop down to F32 for a bit and see if it is repeatable like that.
Also Clonezilla lol
