Is it possible to givebirth to twins lly if twin A is breech - (twin b is vertex)?

so i am scheduled for a cesarean for monday and i really dont want it because i no that the recovery time is longer and i cannot take narcotics for pain relief, so i wanted to know if its possible to give birth lly given my cirstances.....i dont know the risks and i would really prefer a natural birth so anyone who has any info regarding this i would appreciate some advice, thx in advance!
