Not that I'm aware of. I'd be surprised if those machines were even usable outside Amazon's datacenter; they're likely to lack a lot of standard interfaces (certainly no display output, probably no Ethernet, USB, SATA, or PCIe, possibly no 120/240V AC input).
Precisely today, given the lack of SBCs stock and the price rises, I was checking small routers as options. I.e., a basic mikrotik router is 30 something euros, and in some models it supports OpenWRT.
Some of their more powerful routers have a bunch of ARM cores (no video out, though) and I think I've seen people using OpenWRT there.
For a while they were using Annapurna Labs CPUs, and I've seen that in some high end Netgear wireless routers from 2017, and I see people selling those with OpenWRT on eBay. I don't know their performance, but I'd like to try that instead for a mini server instead of an expensive and virtually inexistent RPi.
There goes a list of routers with Annapurna Labs processors, I'll see tomorrow if I find around some OpenWRT builds for them.

Considering modern AWS hardware relies heavily on Nitro, their dedicated chips offloading networking and storage, it's unlikely Graviton CPUs would easily work outside of AWS' environment.
