No. If you hire the solicitor known as Mr Loophole, at considerable cost, he might try to argue that the camera wasn't legal or some such but the argument isn't guaranteed to succeed. You hear of his successes, but it's a fair chance that he usually tells clients to plead guilty and go for avoiding disqualification or points unless he can see a clear 'loophole'.
But you've been given a lifeline if you've been offered a speed awareness course. You choose the nearest one that's convenient, do the course, and you don't get any points on your licence; it's as though the speeding never happened.
