Only with digital not with film, as you run the risk of the film
moving.

push the little button and the transport is disengaged.

It can still move slightly, ideally it shouldn't.

Depends on the design of the camera. In the manual for the Canon FX
(1964-1969), you first use the rewind crank to get the film taut, then
while holding the rewind crank with one hand, you press the rewind
clutch button on the bottom of the camera with the other hand, and with
the third hand, you operate the film advance lever while holding in the
rewind clutch with the second hand and keeping tension on the rewind
crank so the film doesn't move. Operating the film advance lever
disengages the rewind clutch, so you have to hold it in.

Not being familiar with every camera ever made, I assume there are
cameras where the method is simpler.

My Minolta was the same. I don't remember reading about the method in
the manual, though, I think they said nothing. I just found it by
experimenting.

There was some risk of the film actually moving a bit backwards. But the
rewind had to be a bit taut, or the clutch would not disengage and the
film could move a bit forwards.

Tricky.

I can remember some view cameras in the past which had the shutter, and
shutter release on the lens with a cable release (before that they used a
squeeze bulb). In that case the shutter had to be set in much the same way as
the hammer on a single action firearm. With those deliberate, double, or
multi exposures on a single plate, or sheet of film would be possible without
worry of moving film out of frame register.

Yes, I have some old cameras in which the shutter "arming" is not linked
to the film movement. Double exposures were a risk, by accident, when we
forgot to wind them. So we had to train ourselves in the routine of
winding the film just after shooting. And not arming the shutter till
needed, so to avoid storing the camera with springs tensioned.
