No, it is not resolving problem. I tried with alpha.replicaCount=3 and effect same, second replica continued staying in not ready state.
As I know, statefulset will not create third pod until second does not come in ready state.
I setted additional fullnameOverride: dgraph variable for release name overwrite.
Disabling it does not have effect too.
How else I can check why dgraph replica not come ready?
