What RISC-V calls "machine mode" is what the Zephyr documentation refers to as "supervisor" or "privileged" mode.

You don't need to do anything.

It seems to be the case that this collides with some RISC-V specific term?

That's right! In RISC-V terms, Machine mode has access to all system resources and is the
mandatory mode to implement. Supervisor mode has a different usage model, which I guess
used for virtualization.
