In a 6-quart Instant Pot, stir together the water, oats, salt, cinnamon, nutmeg/clove optional (and maple syrup). Cover and seal.
Cook on HIGH pressure (manual) for 5 minutes. Let the pressure release naturally for 10 minutes. Carefully remove lid.
Give the oats a big stir. Carefully taste (they will be hot!) and add additional cinnamon and/or maple syrup to taste. The oats will continue to thicken as they cool.
Ladle into serving bowls and serve hot with any desired toppings.
