No a normal service will not affect it at all. If however there is a “software update” and they apply it then it would. I don’t worry about it as I don’t use VWCV centre for my servicing, but a top notch independent specialist. I ask for a service that is what they do, to the book, no bullsh1t3 software updates, which lets be honest are never for the good of the owner - just yet more power turn-downs to get over yet more VW scandals.
