Can you change the default capsule collision?

Messing around with the ThirdPersonCharacter object, and I’m wondering how to change the capsule collision to a different shape. Is this at all possible?
Alternatively, is there a work-around to avoid the rounded bottom affecting movement?

You can’t a change capsule collision into another one, e.g. box collision. However, you may introduce some additional box collisions just for the movement if you don’t like rounded bottom. Then you would need to setup these new collisions not to interfere with the original capsule and make the capsule ignore the floor or similar so that it does not affect the movement.
