Welcome to the forum.
You should try to dump the bios (at least the Bios_region) with the correct Intel FPT tool, from ME FW package
and use this guide/tool for possible unlocked items available/not showing.
A manual edit in another platform but similar steps:
[GUIDE] [UPDATE] Usage of AMI’s AptioV UEFI Editor + FPT Flash Method - BIOS/UEFI Modding / BIOS Modding Guides and Problems - Win-Raid Forum (level1techs.com)
Branded machines like HP have a difficult security issue to bypass mod files, it may be possible to write the a mod of the bios region only, if a jumper is present on the board (ME_Disable / Factory_Mode / Service_mode, etc…) but general rule it needs to be written with an SPI programmer…and nothing is granted.
Good luck.
EDIT: Yes FDO, sry i cant remember all OEMs jumpers…
By your remarks you’re not familiar with this tools and seems to lack experience on this field, i do not encourage you to procede more and i will not provide further guidance to unexpereicenced users, sorry.
