Kubesphere external monitoring type setting in values file is not working

[KR411-prog]

We are using our own monitoring stack. We want to avoid scenarios like when we reinstall Kubesphere, it should not bring back Kubesphere's Prometheus and conflict with our Prometheus deployment.

But when we choose monitoring type as external in the helm chart values
https://github.com/kubesphere/helm-charts/blob/master/src/main/ks-installer/values.yaml#L76 we are facing errors in the fresh Kubesphere deployment.

E0516 18:37:14.984475 1 notification_controller.go:113] get /, Kind= informer error, no matches for kind "Config" in version "notification.kubesphere.io/v2beta1" F0516 18:37:14.984537 1 server.go:339] unable to register controllers to the manager: no matches for kind "Config" in version "notification.kubesphere.io/v2beta1"

kubesphere controller manager goes into crashlooping status because of this error.
We need a reliable method to disable internal Prometheus so we can run external Prometheus without any issues.
