All those options are talking about Secure boot keys.
Turning off the Secure boot is not an issue. The user has
done that, but the exact same USB Flash that boots fine
on a 3070 doesn't show up as an option on the 3080.
He can take a hard disk from a 3080 machine, install it in
a 3070 machine, boot from the exact same USB on the
3070, and create and image with the 3070. The exact
same USB does not show up on the 3080 as a boot option.
Yes, it is not currently an EFI Flash so would not show up
as a UEFI Flash boot option, but it also doesn't show up
as a regular USB boot option.
You seem to be stuck on harping about turning off secure
boot, but that has been done with no problem.
A lot of the problem is that you are being very unclear about what
you're doing and it's very hard to follow. Now what you're saying is
that a non-EFI flash drive doesn't boot on an EFI system. Why do you
need to point that out? Unless you can enable legacy or CSM mode, it's
obviously not going to work. And newer systems don't have that option
any more.
Also, you apparently ignored the part where he told you that there is no
point in trying to use grub-install. It's not useful for EFI. You just
need to copy a few files into the right directories.
