Dell 7680: can a CAMM unit be upgraded to use SODIMM ECC DRAM?

I am thinking of buying a Dell 7680 from Dell Outlet.

The most common configuration that shows up is one which has:

CPU = Intel Core 13th Generation i5-13600HX Processor and 

DRAM = 16GB (1X16GB) 4800MHz DDR5 Non-ECC CAMM Module

I am OK with that CPU.

But the DRAM will not work for me:

--it is way too small

--it is unreliable (non ECC) DRAM; ECC DRAM is an absolute requirement for me

--it is a CAMM module (good in theory, insanely expensive in practice)

I know from doing this custom config of a 7680 that this CPU supports SODIMM ECC DRAM.

What I need to know is if I buy a 7680 that was originally a CAMM version, can it be upgraded to use SODIMM DRAM?

I think that their used to be an official way: a web search found this:

    Upgrade Dell 7680 with 32gb CAMM to 96GB SODIMM = Success!

From that link, It seems that Dell used to sell an official CAMM --> SODIMM interposer board (part number RN12H).

Unfortunately, Dell seems to have dropped that part.

I think that you can buy 3rd party replacements like this.

But I would not gamble on this.  One reason being that I value Dell Pro support and its warranty, and would never do anything to void that, which this might.
