What does gossipsub's report_message_validation_result do if validate_messages is set to false?

[ShahakShama]

In my application, I want to use gossipsub with validate_messages set to false, but still use report_message_validation_result with MessageAcceptance::Reject In order to reduce the score for peers that sent invalid messages

Is this the correct way to do this? Does report_message_validation_result work regularly if validate_messages is set to false or will it cause undefined behaviour? Is there a different way to update the P4 score?
