This is usually caused by the firmware reporting a failure when trying
to set an EFI variable.
It is unclear that this is in actual issue in GRUB.
What is the age and model of the system in question? Older firmware are
known to have buggy EFI variable implementations where the variable
storage space fills up and they fail to perform garbage collection
correctly.

Using rescue mode, I was able to create an EFI entry for the disk-
based boot loader without problem:
ubuntu at tatanga:~$ sudo efibootmgr -c -d /dev/nvme0n1 -p 1 -l \\EFI\\ubuntu\\shimaa64.efi -L "ubuntu"
efibootmgr: ** Warning ** : Boot0007 has same label ubuntu
BootCurrent: 0005
Timeout: 5 seconds
BootOrder: 0000,0005,0006,0001,0003,0004,0007
Boot0001* UEFI: Built-in EFI Shell
Boot0003 UEFI: PXE IPv4 Intel(R) Network 18:C0:4D:82:E0:C8

Boot0006* UEFI: PXE IPv4 Mellanox Network 0C:42:A1:52:2D:01
Boot0007 ubuntu
Boot0000* ubuntu
This was my second attempt to deploy the node; the first one failed
with a message to the effect that it was unable to delete Boot0000
(which was an "ubuntu" boot-to-disk entry). I used rescue mode to
delete that entry without problem.
