Screeching control panel on closing pop top

2019 Ocean T6 - the control panel has always screeched on final stage of pop top closure (our previous van didn't). Mentioned this several times on service/warranty thought it had been looked at but never has I was even told it wasn't covered until the warranty! is this something that I should be worried about or I can fix. Thanks

There is a very definite change in pitch and volume for a few seconds before powering off the roof system. I ‘think’ this is normal and nothing to worry about
