No. Dusshera (Vijayadashami) is a Hindu festival celebrating the victory of Rama over Ravana. Jainism does not observe Dusshera as a religious festival. Jains focus on their own festivals and observances (like Mahavir Jayanti, Paryushan, Diwali for some communities, etc.), but Vijayadashami is not part of Jain dharma.
