Error parsing arguments: Error loading options: InvalidString(InteriorNul(14))

Placed the setup_var.efi file in a flash drive with EFI boot file.

fs1:\> setup_var.efi --help
Error parsing arguments:
Error loading options: InvalidString(InteriorNul(21))

This may due to how the EFI shell handles arguments. Have you tried using another shell?
