Adjust Istio metrics -limit dimensions

Question

Problem

I am trying to modify metrics so that some of them have less dimensions than the default ones. I follow examples from here. My code looks like:

apiVersion: install.istio.io/v1alpha1
kind: IstioOperator
metadata:
  name: my-istio-operator
  namespace: default
spec:
  values:
    telemetry:
      v2:
        prometheus:
          configOverride:
            inboundSidecar:
              stat_prefix: istio
              metrics:
                - name: requests_total
                  tags_to_remove: ["destination_canonical_revision"]
            outboundSidecar:
              stat_prefix: istio
              metrics:
                - name: requests_total
                  tags_to_remove: ["destination_canonical_revision"]

How I understand the code, now the istio_request_total should not have destination_canonical_revision dimensions, however it does have. Please let me know if I am doing something incorrectly or this is a bug.

Versions

Kubernetes: Azure Kubernetes Services (1.20.9)
Istio 1.11.4 installed with command istioctl install --set profile=demo -y

Solution

It did not work because I was using kubectl to add IstioOperator. After I switched to istioctl, everything works as expected.
