Yes. In a practical/social sense, a person born in a Jain family can choose another religion.

From the Jain point of view, religion is connected to right faith, right knowledge, and right conduct. So if someone stops following Jain Dharma and accepts another path, society may say they have changed religion.

However, Jainism teaches that one should thoughtfully follow the path of Ahimsa, Satya, Aparigraha, and self-discipline. The decision is personal, but it should be made with full understanding and respect.
