Depends on the car. Some H shifter cars have transmissions that subtly penalize the timing using sequential shifting/paddles and leave H-shifter alone.

That said, SRS servers certainly allow paddles for every car, as I don't have an H-shifter and I participate in whatever. My guess is that if you have an H-shifter assigned in your controls, multiplayer mode will force you to use that. If you don't want to use them, save off a config that doesn't have your H-shifter assigned and you should be good to go.
