I once encountered this on a steep gravel incline.  I backed up about 50
meters and took the steep incline at a higher speed.  The traction control
activated a couple of times but I had enough inertia to get past the
slippery spots.  I've since traveled this incline with new tires and the
traction control does not activate.

Snow tires, or (better), do not drive a Prius on un-paved roads.  It is
not an off-road vehicle.

That would exclude about 95% of the roads in North Dakota and South Dakota
and 75% of the roads in Minnesota.  Off-road means "not on a road."  An
unpaved road may well be graded, crowned, and covered with aggregate.   I
believe the OP was on a gravel road.

Correct, I was driving uphill on a well constructed road covered with
stones about 1/4 inch. This road was easy to drive with a hand shifted
car, we did it always in 1st gear. I don't call that road 'off road'. It
is there for about 80 years.

Sorry, my bad.  I should have written, "Try going slower.  The drive
system of a Prius makes it impossible to stall the engine.  I go up
slopes at 1 or even 0 MPH on the speedometer.  Or, stay on paved roads,
or get grippier tires.  I do not have a specific tire recommendation".
