Hi. I have notebook hp pavilion 16-a0021ur. I want to expand the thermal package. Up to 80w. Can I flash vBIOS from similar mobile graphics chips? For example, 10DE-1F11 or 10DE-1F15.
I have tried modifying my vbios with "Mobile Pascal TDP Tweaker 1.21", but I cannot pass verification in nvflash. My dump is correct and successfully flashed through nvflash. I understand that the modified vBIOS can only be flashed through the programmer.

Hi friend,
HP have the RSA check bios internal so are not moddable, from 2015 so far ...
Only an older version may be is moddable.
But your has the older one to 2020 :

Type:BIOSVersion:F.03 Rev.AOperating systems:Windows 10 (64-bit)Release date:Jun 18, 2020File name:sp105583.exe(11.8 MB)
Description:

This package provides an update to the System BIOS. The update installs on supported computer models using a supported Microsoft Windows Operating System. Restart the system to complete the installation.
