Than things are tricky. Ice release is a KKG and can’t be copied with sharingan. And Sasuke definetly wasn’t born with it.

Also during the chunin exams Sarada still had just one tomoe in her sharingan, at that was during the Momoshiki arc.

Ao arc happened not too long after.To go from one tomoe to 3 in such a short time is pretty unusual and honestly, unlikely.
