Sorry, but apart from business notebooks and some high-end gaming PCs, accessing Advanced BIOS option on HP PCs is not possible.
Some OEMs lock out the advanced BIOS options to prevent customers from making changes to options that can destabilize or otherwise damage the PC -- and then send it back for repair under warranty claiming they did nothing to it.
I know only SOME of the advanced options are risky, but it's simpler to disable access to ALL advanced options than to allow/disallow on an individual option basis.
That's the course of action that HP has chosen.
