The back up assist rods are driven by pressure and vacuum form the (PSE) locking pump under the passenger rear seat just as your locks are. They are activated from a signal by the back up switch. The rods are vacuum elements and are the orange hose on the pump (RH). I guess you could remove the hose and cap the pump, being very carefull not to break the nozzle it will be over $300 for a pump. You also could plug the ends going to the actuators on each side, mine usually go up quickly, but retract slowly 15 sec or so.
