I had two bone-in pieces of pork in the freezer that I wanted to use up. One was a nice sized center cut loin chop and the other was a small piece of butt steak. I cooked them together in the Instant Pot. After browning each piece, one at a time, with the sauté function, I added the onions and garlic and sautéed for just a minute, deglazed the pot with a little dry sherry, added the gravy (see PS below) and mushrooms and returned the pork to the pot. I cooked them on Manual at High Pressure for 8 minutes with 20 minutes Natural Release. Both cuts of meat were tender enough to cut with a fork. We each had a portion with our dinner tonight.
PS: The gravy was leftover from the freezer and the leftover gravy from tonight went back in!
