Need to add fields to the values.yaml to conditionally enable / disable creating each of the network policies.

Each will need values.yaml fields for extraIngress: [] and extraEgress: [] which will be appended to the list of rules you are putting in the NetworkPolicy manifests.

Something like this pattern maybe?

controller:
  networkPolicy:
    enabled: true
    extraIngress: []
    extraEgress: 
      - podSelector:
          matchLabels:
            foo: bar
