Yes, you can. Simply prepare the filling and cool, then refrigerate in an airtight container for up to 3 days. Stuff the peppers with the filling just before you want to eat them. With the cold, pre-made filling, I would suggest not pre-cooking the peppers but air frying them (once stuffed) for around 15 to 20 minutes so that the filling has time to reheat thoroughly. Check on them half way through and regularly afterwards to make sure they're not burning. I'd also suggest adding the cheese around half way through cooking.
