Meanwhile, place the tortillas on a baking sheet that goes in the air fryer.
Divide the sauce in half and spread half on each tortilla leaving 1/2 inch of room from the edge of the tortilla.
Sprinkle each tortilla with half of the oregano, salt, and pepper.
Divide the mozzarella cheese in half and spread over top of the sauce. Sprinkl with half the Parmesan cheese on each pizza.
Top the pizzas with pepperoni.
Carefully place the baking sheet 3-4 inches from the top of the air fryer and cook for 6-8 minutes. Keep an eye on the pizza. It's done when the cheese is melted and the edges of the tortilla are crispy and brown.
Remove from air fryer and cool for 2 minutes before cutting and serving.
