Original board identifiers (DMI data):

• Serial Number (S/N): 1TNP50RNC2Y003400274
• MAC Address: D493931E3D2F
• P/N: 6-77-NP50RNC2Y0-D02-A

Thank you.
But this file is just the stock BIOS from the official Gigabyte website — I already know this version and I have tried flashing it before.
The laptop does not boot with this image at all, because it does not contain my board-specific data (DMI, serial number, UUID, MAC address, MSDM key, etc.).
I do not need another copy of the stock BIOS.
I need help rebuilding a working BIOS using my original dump, with my own identifiers preserved and the ME region properly cleaned.
Only a rebuilt image based on my dump will allow the laptop to start.

Try, BIOS from Gigabyte website according to S/N
S/N from your BIOS (back cover) SN23411J005307
According to that S/N on Gigabyte website says G5 (2023) G5 MF5 (DDR5 RAM)
BIOS ver. FB06 (same as your backup)
DMI 10CC000-10CC02F

(DMI, serial number, UUID, MAC address, MSDM key, etc.).
I do not need another copy of the stock BIOS.

BIOS from post 2 is for G5 MF with DDR4 RAM, that's why it doesn't work for you..., your original BIOS is "NP50RNx2-Y" (DDR5)
Only S/N and UUID on your backup, no Win key, MAC address is built-in the Realtek NIC
"Properly cleaned" ME is already on the "stock" BIOS from Gigabyte, try the one I attached
First boot may take some minutes, give it time
