Ryanair only offers non-protected, self-transfer flights. Unlike connecting flights, which fall under the same booking reference, non-protected transfers have to be booked separately and aren't protected by the airline if there are any delays or cancellations during your journey, according to Skyscanner.

A self-transfer flight is a trip that combines multiple flights into one itinerary, where each flight is booked separately as an independent ticket. This means that you'll need to check in, collect your baggage, and re-check it for each flight. (Tripadvisor)
