Firstly you can defend the charge and get acquitted. There would then be no penalty such as disqualification. This assumes you have a valid defence and the Judge finds in your favour. Secondly if you have no defence and have to plead guilty you could apply for a discharge without conviction. This is rare when a charge carries a minimum statutory penalty such as disqualification. But it does happen if you can satisfy the statutory criteria. Thirdly if you have a history of disqualification you may be able to get a community based sentence substituted for disqualification. This is what lawyers call a section 94. And fourthly there may be special reasons that allow the court not to impose a disqualification such as not driving very far or just reparking the car.
