No (although they all have software written Python, likely could work with RISC-V boards under Linux too).

My comment was answer to "what if you could build your own ?". It's possible already, without RISC-V, which is just a different CPU arch.

P.S. I plan to experiment with running Bitcoin node on RISC-V one day, so far haven't found any boards I like. Running nodes on different archs is more important than air gapped devices, where priorities should be security and cost, CPU arch is not so important.
