Some Ryzen boards support ECC RAM, though the support is somewhat unofficial. I'm using 64 GB of ECC on an ASRock X570 Pro4 and it works fine. It's not the cheapest motherboard or the cheapest memory, but I'd say prices for both are in the consumer range rather than the clearly-for-business-only range.

Thanks, have you run any tests to confirm it is working? I’d be more comfortable with a guarantee from the manufacturer but confirmation an ok second choice.

Yes. I originally bought this board with a 3800X and 64 GB of inexpensive non-ECC RAM. That configuration worked fine. I later upgraded to a 5950X CPU, when I needed more CPU power and cores for some software I was writing. After upgrading, I occasionally got memory errors under very heavy load, with the same memory that had been fine with the slower CPU. I upgraded to ECC memory, and it fixed all the memory errors. The memory tested correctly as ECC in all the tools I tried, and also solved an actual stability problem I was having, so I trust it.
