It should be like:

.update(
  query,
  new BasicDBObject(
    "$set",
    new BasicDBObject("STUDENT_001.hobbies.01.isChecked", "0")
));

here query to match the document. and $set is update the field in the path specified i.e "STUDENT_001.hobbies.01.isChecked"

Thanks for your answer Jayaram Pradhan, but problem is that STUDENT_001 is hard coded here, is there any way to use this dynamically.

MongoTemplate mongoTemplate;

mongoTemplate.updateFirst(
        new Query(Criteria.where("STUDENT_001.hobbies.01.isChecked").is("0")),
        new Update()
            .set("Update field name", "Update value"),
        yourObject.class);
