Error on installing Istio - Failed to apply manifests

I am trying to follow this doc. But when I try to execute this command:

istioctl manifest apply \
  --set values.gateways.istio-ingressgateway.sds.enabled=true \
  --set \
  --set \

I receive the following error:

Run the command with the --force flag if you want to ignore the validation error and proceed.
Error: failed to apply manifests: unknown field “k8sIngress” in v1alpha1.GlobalConfig

Ms istioctl version is 1.6.0
