[Request] Bios mod microcode add 12900k ES - qx7e w/ DDR4/DDR5

Hi to All!!
Made the mistake of purchasing a 12900k es chip now bought another motherboard to try to make it work
I’m using UBU to add the microcode 90671 to bios, although it appeard to work, for some reason the pc wouldn’t post either way, and I supposed it was because of DDR5
Now in second motherboard I have been unsuccessful to add the microcode. But maybe I’m doing it wrong… What would be best way of adding microcode…?

cpu90671_plat82_ver0000001C_2021-06-14_PRD_41B7E16B.bin

I have a qx7e intel chip and a i3 12100f for testing
MB2 - PRIME-B760M-A-D4 from ASUS

MB1 - z790-aorus-elite-ax v1.1 from Gigabyte

Can someone supply a modded bios for the two motherboard for me to test a sure bios…

Thanks

MMtool, UEFItool or hexedit mcode same size/replace/swap, working bios region only preferable.
Having full spi backups and a programmer for recover.
ME FW version will have something to say in some bios/es cpus…
