How can i change physics type in PHAT?

Hi, I am trying to create a ragdoll but i can’t get the character the fall on the ground when i simulate physics. My character has some kinematics setup on the bodies and some custom profile physics on some other bodies in the PHAT. When i try to set physics to simulate, the character’s bones do simulate but the kinematic bones stay kinematic. How can i change the state of these bones from kinematic to simulated with blueprints and enable the physics to get my character to fall on the ground like a ragdoll?
