Azure file sync, avoid duplicate files

Hello guys,

I've a share with 2 server endpoint with Cloud Tiering enabled in Azure file sync environment, unfortunately on this share are created duplicate files with the name of the server endpoint so it means that the same file are opened by users on both endpoint. 

My question is if it's possibile to set priority on these endpoint so the users can connect only to the first endpoint server unless this is unavailable then the second endpoint can be use.

Or there are other method to avoid this duplicated files?

thanks
