Отдельная служба для тех же модулей реплик Statefulset

Question

У меня простой Statefulset с 3 репликами / стручками.

the pg-master-0 is the actual master and the rest (pg-master-1 and pg-master2) are standby servers or slaves.

Please ignore the naming i'll be working on that soon

So I have 2 Services

Question : In the current NodePort service if i goto or connect to IP:30006 I am connecting to pg-master-0. Is there a way for me to create a separate service like a LoadBalancer that handles my request for ONLY pg-master-1 and pg-mastr-2 actually all replicas except on the pg-master-0?

I'm planning to create separate service for them but the problem is they all have the same labels
