How to some disable kong plugins for internal microservice communication?

We have around 8-10 microservices (java based spring boot apps) in our architecture. All of them are deployed as docker containers. We have a central kong api gateway that routes the incoming requests to the appropriate microservices. We have central authentication, rate-limiting, monitoring, load balancing and circuit breaker enabled on kong.

How can I disable certain plugins in kong like authentication when the api calls are internal?
