Looking for DJI to respond, does changing the Upper Aircraft Cover Shell void the warrantee?

Because you have to unseal the screws, it is kind of a deal breaker for warranty.
Interested to read DJI's opinion

Hi, thanks for the inquiry. Modification of the drone would possibly void the warranty, however, this will depend on the result of the repair service center. For further details about our after-sales service, please refer to the link below. Thank you for understanding.
