Admin-api service endpoints, loadbalanced?

Right now, we have an upstream called admin-api with 2 static ip’s listed as a target.
It isn’t used right since the service we have created for the admin-api has 1 static ip, meaning it goes to 1 of our 2 nodes.

What is the best approach?
Is that to point it to the upstream and use kong’s internal load balancer or to use HAProxy on an internal hostname to load balance the requests?

Refer to the doc: Set Up Intelligent Load Balancing - v2.3.x | Kong - Open-Source API Management and Microservice Management

Thanks, that part i’m aware of.
IT doesn’t say if i should do the same with Admin API.
