Sir, just to let you know that I have tried

"sp54077_AdvMenu_ByCamiloml"
and
"sp54077_NWL_ByCamiloml"

Both of them are giving me black screen after reboot, just like my eGPU

Ok, i have two bad news for you.
You said you have black screen after flashing that mod. Your bios is RSA signed (new HP protection to prevent flash unauthorised modified bioses) and you get a black screen every time when try to flash mod.
Only HW SPI Programmer can do this job.I can decapsulate bios image and you can flash it directly into bios chip via HW SPI Programmer.
Second, i strongly recommend do not touch graphic settings (if you will flash mod) because you will get bricked laptop.
