Tell your instructor to get his feet completely off the pedals. If you're about to go solo, he should not be interfering with the controls at all. Not even following through. If he still does that, then either you're not ready for solo by far, or he's not instructing properly.
The beauty of the "land-o-matic" nosewheel steering is that the aircraft will essentially track straight ahead on the landing roll, assuming you had the fuselage and the flight path aligned with the runway centerline in the first place. There is plenty time for the instructor to move his feet off the floor and on the pedals if you do something stupid.
Now if you were flying a tailwheel aircraft, I can imagine that the instructor would want to be able to take control quickly and thus have his feet on, or very near the pedals. But in a nosewheel aircraft with a student who is about to go first solo, no way.
