Can'r change the values of certain BIOS settings with HP.CLientManagement commands

I am writing a detection/remediation script. Some PCs need the setting "Configure Legacy Support and Secure Boot" option to be set to value "Legacy Support Disable and Secure Boot Enable". When I run 

Set-HPBIOSSettingValue -name "Configure Legacy Support and Secure Boot" -Value "Legacy Support Disable and Secure Boot Disable"

it outputs success message but when I run 

Get-HPBIOSSettingValue -name "Configure Legacy Support and Secure Boot"

it outputs the original setting. This is a recurring problem. Any advice?
