man efibootmgr shows a 'label' option but
I've never used it. Try it at your own risk.
If I was going to try it I would first create the
new one with the new label using the data from
an existing option, test it, and if it worked then
delete the one with the less useful name.
From Google Bard:
<QUOTE>
Use efibootmgr -c -d <disk> -p <partition> -l <new_label> -L <loader_path>
to create a new entry with the desired label and correct path to the
bootloader:
<disk>: The disk where the bootloader resides (e.g., /dev/sda)
<partition>: The partition number where the bootloader is located (e.g., 1)
<new_label>: The desired label for the boot option
<loader_path>: The full path to the bootloader file (e.g.,
\\EFI\\ubuntu\\shimx64.efi)
