How to update serviceMonitorSelectorNilUsesHelm values when using OpenShift Prometheus Operators is used

[ajay15283]

If prometheus is not installed from kube-prometheus-stack and instead openshift promethus operators were used in that case how to update serviceMonitorSelectorNilUsesHelmValues to false as the metrics are not visible in grafana dashboard

From Documentation
Our Prometheus installation needs to be slightly customised to discover ServiceMonitors by default. Create a values.yaml file with the following configuration:

prometheus:
prometheusSpec:
serviceMonitorSelectorNilUsesHelmValues: true
serviceMonitorSelector: {}
serviceMonitorNamespaceSelector: {}
