There is no imperative form for the word "мочь", because it refers to the group of modal verbs. It is the same thing with English "can". You can't put the verb CAN into imperative form. But anyway, as Sergey said, we have a synonym, which can be set into imperative form: "суметь" - "сумейте", though it is very contextual and you should use it carefully.

it's a good question)) We don't use it in imperative form. But there is a word "уметь" that can be translated as "can". Then according the rules it calls "Сумей! Сумейте!"

Императив в такой форме: Не моги! — не вздумай, запрещаю, не смей. Пример: А о себе подумать не моги.
