Prevent rewriting specific url by nginx

Hello .

Sorry if my english is not well

I have a wordpress multisite with nginx (actually easyengin)

The wpmudev prosites plugin has a url like this =>

When user click the link , url rewrite to

When user has 1 site there’s no problem but when user has more than one site prosites could not determine which blog must upgrade

How can i prevent nginx to rewrite this url ?
