M4-1015DX Old But works would like to have AC wifi

[questorfla]

I ave almost given up because this laptop is so old that no one seems to have anything for it.  Or rather they did but so long ago that they are no longer available for download.  Hp dropped all support for this unit for Win10 which it runs very well under with the exception of a lousy WiFi chip.
I posted several complaints with Management at HP and was hoping to find that they had finally unlocked the bios on something they will no loner support
If the Powers That Be at HP had not made such a big deal of my complaining I might have stopped looking.  As it is, I am trying to find anyone who can tel me what I need to do to Mod the only bios I have for it (F.23 Insyde) to remove the Whitelist.  I have the exact replacemnet Broadcom Wifi chip that can handle AC but of course the Bios has it white-listed and it is locked to a Ralink chip that I would really like to replace.
Any Help appreciated
