No they are normal bleeder valves. If you are using a helper, he must push the pedal down an hold it while the valve is drained and then closed again. In Bentley they say "Close the bleeder screw and release the brake pedal".
BMW are very conveniently set up for attaching a Motive pressure bleeder. You fill it with brake fluid, attached to a refilled brake reservoir and pump to 20 lbs. Then you just open the bleeder valve until you see fresh fluid. That may explain the lack of availability for speed bleeders.
