Can you get a 6 pack if you have a funnel chest (PE-Pectus Excavatum)?

I am 13 years old and have a funnel chest, i really want to get rid of it but im not having surgery i was wondering if it would go on its own or if their was any exercises i could do or something and if i can still get a 6 pack because ive tried loads and i cant see no improvements i hardly have any body fat aswell.
