HP EliteBook 840 G3 (sp101340) WWAN whitelist removal

[iitztoss]

Hi, today I received in the mail a Sierra Wireless EM7455 LTE card. I now know that my HP EliteBook 840 G3 has a whitelist, but when I ordered this card from china I didn't know. Does anybody know how to mod this laptop's BIOS? 
I installed the card and it's like it isn't there. I can't see it inside device manager and it doesn't give me a bios error code at startup.
I run the HP N75 V1.45 BIOS (https://ftp.hp.com/pub/softpaq/sp101001-...101340.exe). I don't know what manufacturer is this BIOS from, I hope it's not an HP custom one

Hello,
I need to mod my own laptop to remove WWAN whitelist. Could you help me?
Here is my own laptop BIOS dump file:
