You can override the `podTemplate` section of the Elasticsearch spec with pod-related constraints (eg. privilege).

This is likely not going to work. ECK needs to manage the full cluster, it cannot run a subset of data nodes of another existing cluster. Have you considered cross-cluster replication or restoring from snapshot?
