Okay, if I understood you correctly, the disk with macOS boots well with 0.6.6 and 0.6.9. But the USB stick does NOT boot well with 0.6.9.
What can you do now? In my opinion:
You see what the problem is, from the macOS disk the EFIs work fine but from the USB stick they do not run.
Note: in my BIOS there is not any Serial Port or SuperIO entry.

What can you do now? In my opinion:
- you have to use a different USB stick
- delete the Big Sur app from the Applications folder
- download Big Sur again (you can find it in the App Store)
- create the USB from scratch
- mount the EFI partition and copy the EFI 0.6.9 folder into it (you can get @Edhawk EFI or mine)
- boot up and do ResetNVRAM the first time.
- from Disk Utility choose the device in the upper level (not the volume that exists inside the USB)
- erase
- GUID as partition scheme and HFS + as file system
- open terminal and write
sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/USB
(assuming the USB stick is named USB).
