RISC-V is not an architecture, it is just an instruction set. People still need to design the architecture for an implementation of RISC-V.

Intel ME is a co-processor that runs at the same time as the main processor, it is not related to the instruction set.

To answer your question: Intel ME is a problem that happens on an higher level than the document that defines instruction set.

There are "instruction set architecture" and "microarchitecture" (=specific implementation of an ISA). ISA is the one more commonly referred to as just architecture, I think.
