> First, "manually control" engines and rudder isnt a thing.
I think you're taking "manually control" a little literally here. Based on the other comments I saw that used this phrase (or roughly similar phrases), it didn't sound like they expected a crew to strap a rope to the rudder and start pulling.
It sounded more like a way to physically disconnect everything "smart" in the event that it became compromised, and have a way to interact manually with the rudder (now air-gapped) via dumb electronics (probably integrated circuits and an analog pid system) would meet their criteria.
That may or may not be possible for various reasons on modern ships, but what's being implied in this comment doesn't seem to be being suggested.
