The drives are found now, but the partitions do not seem be properly parsed.

One thing I saw was the partition names in the partition table are missing a p before their partition number:

Partition  Attrs   Start Sector    End Sector  # of Sectors System
/dev/nvme0n11                2,048     1,050,623     1,048,576 EFI System partition
/dev/nvme0n12            1,050,624     3,147,775     2,097,152 EFI System partition
....

Hexdump did not work either, because of the wrong naming:

hexdump: /dev/nvme0n11

I found the issue.

ReadEFI needs to be extended.

Instead of:

       label=${drive}$((${i}+1));

We need to create the label for the partion like so:

        PartExt=$((${i}+1));
        if [ "${drive:0:9}" = "/dev/nvme" ]; then
                PartExt="p$PartExt"
        fi
        label=${drive}$PartExt;

And the script works fine for me.
The partition table above works correctly and the hexdump works, too.
