Servers option in open api 3.0

Suppose I have 5 api in my swagger

We have 3 servers.

Now out of 5 only 2 api is applicable to Dev. 1 for Stage , 1 for Prod Env.

How Can I differentiate api using open api 3.0. I want situation like if I selected Dev api then that api will not be ececuted for prod or stage or its turn into hidden.
