I think we all agree that it should theoretically exist, but I've not seen any existence proof in either a paper spec announcement (many embedded boards are not sold directly to consumers) or a shipping device review.

Solidrun/Compulab in Israel announced a DIN-mountable fanless router based on Ryzen Embedded V3000, https://www.solid-run.com/fanless-computers/industrial-embed.... Premium components and proprietary cooling to support 30W+ TDP. Impressive, but probably $1K price tier.
