Dell BIOS swap

I have a Dell T30 Server that uses the same exact motherboard as the Dell Precision 3620, that being said the T30 BIOS stops supporting the M.2 slot on the board after version 1.02 however the 3620 BIOS supports it in all its BIOS updates. The 3620 also has a wider number of supported processors than the T30. Is it possible to flash my Dell T30 motherboard with the 3620 BIOS to regain all the support or am I locked on staying at stagnant BIOS 1.02?

It's not just about LGA775 or X58 Xeons. Later CPUs are supported too.

I found 2 different part numbers, the Precision 3620 uses board # 9WH54 and the PowerEdge T30 uses board number 07T4MC although the boards are an exact match otherwise. I'd like to ask them however I don't know where to post on their page to get the best answer. I just installed an i7-6700K processor in the T30 which it took without issue although Dell doesn't list it as supported. My guess is they want to make extra money so they don't list a full list of processors since they would rather sell a computer than give the business to Intel for just a processor upgrade.
