Is it possible to specify which fields to modify when calling the save method?

Yes, it is possible. In Django ORM, the save() method of a model has an optional argument update_fields.

# Updating only the 'name' field
instance.name = "New Name"
instance.save(update_fields=['name'])

# Updating 'email' and 'is_active' fields
instance.email = "new.email@example.com"
instance.is_active = False
instance.save(update_fields=['email', 'is_active'])

Using update_fields is recommended for performance optimization, as Django generates an SQL UPDATE statement that affects only the specified fields, not the entire model. This is especially useful when working with large models or frequent updates of individual fields.
