Change BIOS settings - WMI - Powershell - Password protected

[Badidou]

I want to change a parameter in the bios which is password protected;
with this code it works fine

$Password = "<utf-16/>"+"mypassword"
$BIOS=gwmi -class hp_biossettinginterface -Namespace "root\hp\instrumentedbios"
$result = $BIOS.SetBIOSSetting("NumLock on at boot", "Enable", "$Password")

but I don't want to use clear password, I want to use encrypted password, how to do this please

Thank you.
