Yes, you can! For Instant Pot Barley, place 1 cup of dried barley in the pressure cooker with 2 1/2 cups of water or vegetable broth. Add a pinch of salt. Lock the lid into place and set it on high pressure for 23 minutes (25 for hulled barley.) Perform a quick release. When it's safe to open the pot, fluff the barley and store for later use.
