The 'Force Disable Collision Between Constraint Bodies' rigid body node option modifies the collision table of the physics asset its used with. It is expected that this option works as an override and should preserve the assets original table.
Create/Use a physics asset with at least two bodies joined by a constraint.
Enable collision between these two bodies, making sure the constraint is not set to disable collision.
Create an animation BP with a rigid body node using this physics asset with 'Force Disable Collision Between Constraint Bodies' enabled and play it in editor.
Result: The physics asset now shows collision between the two bodies as disabled and disabling 'Force Disable Collision Between Constraint Bodies' does not restore the previous behavior.
Expected: The physics asset would remain unaffected.
