So this suggests the EFI grub.cfg is found and loaded, but it doesn't
find /boot/grub2/grub.cfg

So if you can EFI grub.cfg correct, /boot/grub2/grub.cfg should be OK

Mine is:
search --no-floppy --fs-uuid --set=dev c5f18a2c-ee16-454e-b85d-6d7f03b86532
set prefix=($dev)/grub2
export $prefix
configfile $prefix/grub.cfg

Note the difference in the "search" line.  Mine does not have the
--root-dev-only argument.  Other than that they appear to be the same
(other than the UUID of course),  Try editing that out?

After that I think you are deeper into grub2 than my experience goes.
I.e., is $dev getting set correctly? etc.

Another thought, though a longshot.....  Make sure the EFI grub.cfg
has proper line terminators?  I have no idea if grub cares, but mine
has Unix-standard LF.  But I'm wondering if you have CR-LF, maybe it
treats the CR as part of the UUID?  Which then causes it to not find
the UUID?
