Flashing modded BIOS on a Gigabyte B360M DS3H

Hello,
I’m trying to flash a modded BIOS on my Gigabyte B360M DS3H with the Turing ReBar module, using Q-Flash i get the infamous “Invalid BIOS Image” error, using the EFiflash method i get the “Secure Flash” warning, probably because I updated my BIOS to F19 previously and using flashrom the flashing completes but Resizable BAR is still disabled in GPU-Z after using the .exe to configure the ReBAR size.
I should mention my GPU is a 1660Ti
If anyone could give some other method to flash the BIOS or tell me what I’m doing wrong I would be grateful.
