Trying to update BIOS Password through Command|Update without success.

Hi Folks,

I'm getting ready to deploy a master BIOS password to the fleet using Group Policy. I'm investigating using Command|Update, specifically the following command:

"C:\Program Files\Dell\CommandUpdate\dcu-cli.exe" /configure -biosPassword="Test1234"

I'm running it locally to test before we deploy and it returns with a 

'-biosPassword' setting updated with value 'Test1234'.
Settings were modified at 30/05/2023 2:52:32 PM
Execution completed.
The program exited with return code: 0

This would suggest to me that it's working fine, except when I reboot, there's no password on the BIOS.

What am I missing? I've searched through the forums for similar issues, without luck. 

Can anyone spot what I'm doing wrong?
