RISC-V is a processor architecture like x86 or ARM, but the base spec is open source (though manufacturers can make proprietary modifications I believe). There isn't any consumer hardware to my knowledge but dev boards do exist.

Yeah, I don't think ME has changed massively since then, the issues page has information about people trying various boards and specific forks that they used. Basically it takes a firmware image and at a minimum can enable the disable bit (telling the ME to shutdown during boot), you can also tell it to strip as much code as possible without triggering the fail safe (power off after 30 minutes). Not every machine supports a full clean and the ME does sometimes manage stuff like energy saving states, which may not work properly after a clean. With a backup of your firmware though you should be able to revert if needed.
