Audi used car warranty Plus with own brake change

Hello together, I hope I’m right here in the section, otherwise please move! have a vehicle with Audi used car warranty Plus. To do this you have to have service/inspection (repair also?) done in a VW workshop so that the warranty remains. I soon have a service check at such a workshop again and already know that the brakes (dishes and receipts) have to be made new. So if they carry out the check and say that the brakes are new chambered I have to do this with you (or a VW partner workshop) or can I change it myself without losing my used car warranty plus. Or would it be advisable to change the brakes before the inspection so that the topic does not occur at all. Hope you know what I mean! Make your own brakes = guarantee away? Let the brakes be made at VW workshop = guarantee remains? Thank you for your help!
