How to automate silently updating password-protected BIOS?

[B222]

I have bitlocker enabled and bios is password protected. I wanted to automate the bios deployment...

I use SCUP and SCCM. The update I was trying to push out was sp78260.exe
Note: HPBIOSUPDREC and hpqpswd are included in sp78260.exe (you can see this by opening it with 7-zip).

The following command worked (From an admin command prompt):
MYBIOSPASSWORD -> replace with your actual bios password

sp78260.exe -s -e cmd.exe -a /c ""hpqpswd.exe" -s -f"tempfile.bin" /p\"MYBIOSPASSWORD\" & "HPBIOSUPDREC.exe" -s -r -b -p"tempfile.bin" "
