[Paid Request] Adding Epyc 2nd gen CPU support to a 1st gen Motherboard

[TikerLynx]

I have a Quanta T22HF server that came with a rather stripped down BIOS that only supports Epyc Naples (1st gen) CPUs
These are cheap units being scrapped from some datacentre, and would be ideal for homelab use and the like.
I would like to add 2nd and ideally 3rd gen Epyc support to this server.

I have a copy of the current BIOS and a far less stripped down one that was provided by the manufacture that should add Milan (2nd gen) support. But the board will not post if flashed with that file.
Here's a link with those BIOS files and what little else the manufacture would provide:

All the hardware is the same between these CPU generations, and there is no chipset.
The original BIOS file is 16MB and as I said only supports 1st gen.
Epyc BIOS files that support 2 generations are 32MB and appear to be mostly two almost separate files in the same chip.
So Ideally I would like a BIOS that supports 1st and 2nd gen and another that supports 2nd and 3rd gen.

Thank you in advance.

[EPYC]

I also have this server. Using EPYC 7351P and EPYC 7551P. 

BIOS 3A17.01 includes CPUID 00800F12 and 00800F11
BIOS 3B21.Q201_32 00830F00 and 00830F10

Not sure of the BIOS size?

Unfortunately I don't have any EPYC Rome cpus to test yet.
