[REQUEST] HP Elitebook 8440p Whitelist Removal

[lm2]

hello


I have been given few years ago a 8440p, few weeks after a sierra LTE cell card. I can plug it inside. However, the bios rejects it, as the policy of HP product things..
I found then the why, then that bios could be modded..
I saw this topic , with a certain hope

just, really, is that impossible to use a CDMA/LTE module inside of it, because it requires external devices to experience HP bios modding? I have nothing else than the laptop, and I would be a bit disappointed to understand hp fucked me a bit (was a free laptop but... bad behavior) on this side.. is there really no way out to get it supported without breaking the bios?
in addition, could coreboot/linuxbios could run on it?

I thank you vm
bset regards
