The current North American Wall Connector has a 16 position rotary switch and two DIP switches. The manual says to always set the second DIP switch up. This is the switch that is used to require the Tesla digital signaling on the European Wall Connector. I have no idea if it does anything on the North American version.
If you own the Tesla HPWC Gen 2 charge station, it's perfectly fine to move the "forbidden" DIP switch to the other position. Just like the European version, the HPWC will immediately charge J1772 cars, instead of waiting up to 28 seconds for the charge to start.
