Microcodes:
Updated all Microcodes to the latest.
Misc:
Added PKFail Mitgation (PK, KEK, DB, and DBX are all extracted from Bios ver F6b vars, replaced all 4 vars as-is to this bios.), now you could boot using latest Microsoft 2023 Bootloader:
Normal Resizable Bar: Use ReBarSate from here, And Run as Admin.
Nvidia Turing (GTX 1600/RTX 2000): Use this, And Run as Admin.
You need to enable Above 4G Decoding for Resizable Bar and Disable CSM/Legacy (boot to UEFI only). To enable it, go to bios → Setup → Go to the Invisible setting under ‘ATA Port Information’ → Above 4G Decoding and enable it.
*Due to Physical Memory Address is limited to 36 Bit, for system with 32GiB of ram only 8GiB of Resizable Bar Address Possible.
How to Apply the Secure Boot keys with the latest 2023 signed keys and latest dbx (release 1.6.2 from secureboot_objects)
Make sure bios is at UEFI mode only, secure boot enabled, and set it at custom mode, but dont install the default keys, instead, run Apply Keys.cmd as admin included in the folder, and reboot.

As a contribution to this topic, you can try the UEFI NVMe modules I’ve attached, specifically published by Gigabyte, or perhaps even leaked, for this motherboard.
I’m 100% confident they’ll work.
NvmExpressDxe_5
Samsung_M2_DXE
These two modules are not needed.
These modules appear as “PATA SS” in the BIOS Boot Driver List. However, the three modules I’ve attached are compatible with the Gigabyte B75 chipset motherboard BIOS.
The full name and brand of the NVMe SSD will be visible in the BIOS Boot Driver List, making them compatible with all other modules.
The advantage of this is that if you have two NVMe SSDs of the same brand installed and want to install the operating system on only one, a different operating system on the other, or use them as a backup storage drive, there won’t be any confusion between the drives.
I haven’t had the chance to try them on other motherboards with different LGA 1155 sockets due to lack of time.
I don’t know if it will work.
The images below can give you an idea of how to add these modules and how they will appear in the BIOS.
it is not leaked, in fact, Bios F11e of H77 DS3H does have it (native nvme boot), but for anyone who wants to try, just remove nvme and samsung m2 ahci dxe driver from the bios i posted here and use nvme modules from it, i don’t know if it will work since i currently drive sata ssd on B75M HD3 and H77 DS3H.
