How to repair / rebuild GRUB following a cross-upgrade from CentOS 7 to AlmaLinux 8?

The “UEFI Boot Options” are within the flash memory of the motherboard. (The efibootmgr shows these entries.) On normal install the installer creates an entry for AlmaLinux. The ELevate presumably does the same. Four entries … four attempts to elevate?

Why are the AlmaLinux entries unavailable?
What is in /boot/efi/EFI/almalinux/ now?

AlmaLinux entries are not available as its not able to recognize the RAID, probably due to this: ELevate Frequent Issues | AlmaLinux Wiki

I have to verify the /boot/efi/EFI/almalinux contents.
