Mod new UEFI bios to work in HP laptop


I recently accidentally shutdown my laptop while the bios was still flashing. I have been following this tutorial: and have so far been able to get flashrom on my raspberry pi to detect my bios chip and save the current bios to a .bin file. I am currently stuck at the point in the tutorial where I have to modify the new bios, which I got from the hp website, to be able to use it on my laptop.
The problem is, I can’t find a tool equivalent to the one the guy used in the tutorial for modifying the new bios for an hp computer (the one he used is only for asus motherboards).

My question is could anyone help me with modifying my new bios with the correct mac address and other pieces of data retrieved from the old bios?

Any help would be greatly appreciated.

P.S Apologizes if this is the wrong forum to be posting my question on, but I am a total noob when it comes to bios modding and flashing, so didn’t know which other forum is applicable to my case.
