Trying to update BIOS Password through Command|Update without success

Hi,​

​I'm getting ready to deploy a master BIOS password. 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 26.01.2024 15:52:32 ​
​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?​

Also tested with newest Dell Command Update and 4.5.0
