Stir the broth, vinegar, thyme, nutmeg, red pepper flakes, and salt in an Instant Pot. Mix in the frozen pepper strips, then set the pork chops in the pot so they stand up on their sides and lean against each other and the side of the insert with room between each for liquid and pepper strips (in other words, not in a stack). Lock the lid onto the pot.
