Preheat the oven to 400°F. Line a rimmed baking sheet with parchment paper, then spray it lightly with olive oil spray.
In a large bowl, combine 1½ cups of the shredded mozzarella and the cream cheese, egg, pork rinds, oregano, basil, and garlic powder. Mix well then form the dough into a ball.
Place the dough ball in the center of the prepared baking sheet and press it gently into a circle or square 10 to 12 inches wide and ¼ to ½-inch thick. Bake until the crust starts to turn golden, 8 to 10 minutes, then carefully flip the crust and bake until it starts to brown, 6 to 8 minutes more.
Add the marinara, remaining ½ cup of shredded mozzarella, and other toppings and return the pizza to the oven until the topping cheese is melted and bubbly, 4 to 5 minutes. Let cool slightly, then serve.
