How to move from Internal Audit SA to Risk FT at a BB firm?

I've secured a summer analyst position within the Internal Audit division. However, WSO threads have stated how it is easy to become pigeonholed within this function and to get out of it ASAP.

I intend to carry out the ACA if I do convert the IA position to a FT offer but am keen to also get a FT in Risk instead if possible.

How can I go about switching from IA to the Risk division after a summer internship in IA?

Thanks in advance.
