You can add it and remove it from the physics world using

btDynamicsWorld::addConstraint(btTypedConstraint);
btDynamicsWorld::removeConstraint(btTypedConstraint);

Or (once its added to the simulation) you can enable/disable it using

btTypedConstraint::setEnabled(bool)

One funny about Bullet when switching from another Physics Engine is that if the btRigidBody (that the btConstraint is targeting) is not already in the physics world, when activating the constraint Bullet might crash.

So you have to add your RBs first before adding constraints to the btDynamicsWorld.

Just a heads up.
