If you want to manually provide redundant EFI system partitions (no
RAID1), all you need to do is run efibootmgr to add a second entry. You
don't need to install grub2-efi-modules or run grub2-install. Use:
efibootmgr -c -w -L 'CentOS Linux' -d /dev/sdb -p 1 -l 'EFI\centos\shim.efi'
... where the option to -d is the name of the drive containing the EFI
system partition and the option to -p is the EFI system partition number.
For reference, that command will appear in /var/log/anaconda/program.log
after any normal installation.
