Mod for L14 gen 3 AMD 21C6 to remove WWAN card whitelist?

[frankeinstein2532555]

The lenovo WWAN card (Fibocom L860R) costs 231 dollars , i do not want to pay that much for a dumb card that lets me use 4G , i want to use my own card (like the much cheaper Fibocom L860 GL which costs 40$ instead of 231$)
BIOS link(Lenovo .EXE self extractor) : https://download.lenovo.com/pccbbs/mobiles/r1yuj16w.exe
BIOS version : 1.27
Type number : 21C6
