Attempting Installation of Big Sur on Gigabyte B660I Aorus Pro DDR4

Hi all,


I'm looking for some help in completing boot of this hardware with Big Sur:
- Gigabyte B660I Aorus Pro DDR4
- i5 12400F
- Nvidia GT 730 2GB (works with Big Sur)

The Big Sur installer runs through the code until you can see a grey background and the mouse pointer.
At the point the language selection and the installer windows never appear.
I've attached the EFI folder

Does anyone have clues about this?
Thanks a lot!
