[REQUEST] Unlocking Zotac Magnus ER51070 BIOS

[John_Smith]

Hello, I have a A320 motherboard from this Zotac mini pc. I want to ask if it's possible to mod or unlock its BIOS to allow mounting Ryzen 5000 series.
Current Bios version is 5.12 - AMD AGESA SummitPI-AM4 1.0.0.6, it only supports Ryzen 1000 chipset. While doing some digging around about this BIOS I found last year AMD had released AGESA V2 PI 1.2.0.7 microcode out to vendors, and more companies had upgraded its A320 motherboards BIOS to support newer Ryzen chips.

So maybe now it has became possible to upgrade this BIOS AGESA as well using one of those BIOS as reference? Apologize if it's a naive question but I really want to know if that's possible. I would do it myself if I could, but I don't know how to inject CPU microcode to BIOS, upgrading AGESA doesn't seem like a matter of just injecting CPU microcode either.
I have attached the ER51070 bios down below, thank you!
