Can you suggest Blueprint for "dynamic" editing of Collision Capsule properties?

Question

2D

Tell Blueprint to "dynamically" edit the properties of the Collision Capsule, so that, for example, while on the stairs, the dude passes through objects with a collision, but, say, does not rest his head on the ceiling, or could he jump through the "floor" to a lower level. Or how to do it in 2D Side Scroller?
