Return with full-year tyres instead of summer tyres (leasing)

Hello together, summer is coming to an end, autumn is about to start and for some people the topic of winter tyres will certainly be the same. That’s why I don’t want to talk about it further here, but we will install good all-year tyres (GJR) on the factory rims. So the summer tyres installed from the factory are left. Now I have studied the leasing contract and can’t find any information about whether a return has to be made on summer tyres. There is no “summer tire”, this only applies to winter tyres (snowflake). So I don’t think this would have to be a problem/deficiency. Also the VWFS damage catalog does not give anything: https://damage catalog.vwfs.de/maturation.html How do you see/do it?
