In the bowl of a stand mixer equipped with a paddle attachment, cream the cream cheese for 3-4 minutes or until nice and smooth and there are no lumps.
Scrape the sides and bottom of the bowl.
Add the sugar, flour, and nutmeg and mix on high for an additional 1-2 minutes.
Slowly, pour in the Rumchata and heavy whipping cream and mix on low speed until combined then slowly increase the speed to high and mix for about 1 minute.
Add the eggs in last, one at a time, mixing just until the yolk disappears into the batter.
Carefully pour half the cheesecake batter in the prepared pan and tap gently on the counter to remove any air bubbles.
Spoon half of the strawberry swirl on top of the cheesecake and use a toothpick to make a swirl pattern. Repeat with the remaining cheesecake filling, and top with the strawberry swirl.
Cover the cheesecake completely in aluminum foil.
Add a trivet (preferably with long handles) into the instant pot along with 1 cup of water.
Place the cheesecake on the trivet and place the lid on sealing.

Allow the pot to naturally release for 10 minutes.
Remove from the Instant Pot and allow the cheesecake to cool to room temperature then transfer to the refrigerator to set overnight.
