T2 Mac serial shenanigans

Hi, so I have an interesting problem. Got in a liquid damaged 16 Inch MacBook Pro for a customer for board repair. Well there is no fixing this thing, it is toast. I sold him an exact replacement 16" as I had a used one. Well he called me next day saying his professional software he uses for work doesn't want to activate. Turns out its bound to a particular serial number. And the company said its like 1000EUR to get a replacement licence (he told me its a 15k piece of software). Not great....

Is there any way to transfer the Serial? On the old Macs I could just reprogram the EFI flash chip and it was a done deal. Well this doesn't seem to be the same on T2 enabled machines. I did see two videos using this programmer (https://www.unionrepair.com/by-t200-t2-data-assistant-for-macbook-read-backup-repair.html), but I have no idea if this is even real (I mean it was just on YT) and if this specialty programmer is the only way to do this... I don't want to drop 200EUR (with import and shipping) to find out this was all complete BS.

Anyone ever tried this before?

It's a regular 25-series SPI ROM but 1.8V and in a USON 3×4mm package. The above adapter should have the correct footprint and an integrated level shifter, but you could also use a programmer with native support for 1.8V (or a different level shifter) and solder wires to the chip…
