Update navigation manually on dynamic navmesh

I need to change the radius of a Sphere Collision on runtime. That sphere collision is a dynamic obstacle with an AreaClass of NavArea_Null. I want the navmesh to adapt to that change. If I only change the radius, the navmesh doesn’t update. However, if I move the object, the navmesh does update correctly.

Is there a way to tell the navmesh to update the sphere collision?
