[REQUEST] Lenovo Thinkpad T540p (GMETxxWW) Whitelist Removal

[Dudu2002]

Hello.

I'd like to request a WIFI/WWAN Whitelist removal and menu unlock. I have attached SPI Dumps from both chips in the motherboard.

Current WIFI card is a Intel 7260NGW with a PCI ID of VEN_8086&DEV_08B2&SUBSYS_C2708086

Thank you for the help in advance.
