Add the trivet to your Instant Pot.

Place the pumpkin, sweet potato, onion, bacon, water, salt and pepper, and butter.

Place the lid on the Instant Pot and lock. Make sure the vent is set to 'sealing' position.

Select manual or pressure cook (depending on which model you have) and select High Pressure and set the timer for 10 minutes.

When it is finished, release the pressure with the quick pressure release. Remove the lid and let it cool

Then add Carnation milk.

Pour mixture into a blender and blend until smooth. You could also use an inversion blender.
