To enable any of those operator you need to edit the clusterversion resource using oc edit clusterversion and then remove the respective overrides group block. Ex. if we want to enable monitioring then following block should be removed from the clusterversion

    - group: apps/v1
      kind: Deployment
      name: cluster-monitoring-operator
      namespace: openshift-monitoring
      unmanaged: true

$ oc get clusterversion version -ojsonpath='{range .spec.overrides[*]}{.name}{"\n"}{end}'
cluster-monitoring-operator
machine-config-operator
etcd-quorum-guard
machine-api-operator
cluster-autoscaler-operator
insights-operator
prometheus-k8s

$ oc patch clusterversion/version --type='json' -p '[{"op":"remove", "path":"/spec/overrides/<unmanaged-operator-index>"}]' --dry-run  -oyaml
