Running a line in or above a wall with insulation.

I need to run power across 3' of an exterior wall (inside) that has cellulose insulation.

This is inside a knee wall so its an unoccupied area.

Do I remove the insulation, drill holes in the studs, run the wire, then patch up the cellulose or is it acceptable to run it across the face of the studs and insulation using staples.

You cannot run cable on the face of the stud if it will have drywall over it. However, you can notch it, install cable, then cover it with nail plate.
But for 3' run, removing drywall and drilling stud is just about the same amount of work.

You may or may not have to remove cellulose insulation cause it might compress enough to allow cable to run across. If not, just cut insulation along the path of the cable, and put the cable in between.

Can you run behind the knee wall?

No drywall, it's an area behind a bedroom, no access except through a small opening, not used for storage, anything.

The area to cross is studs and cellulose insulation, nothing else!
