[REQUEST] Lenovo Legion 5 15ACH6H unlocked Bios (since bricked stock)

Hi all, I need to hardware flash (with ch341a, have done before) a bios and since I'm at it I want to unlock.
The laptop is Lenovo 5 5800h + 3070 (Model 15ACH6H) and here is the .exe installer link of the latest bios.

Thanks, Have a Nice Day!

P.S. Hope is the right sub-forum, I'm not sure bios is phoenix or other manufacturer.
