To uninstall the dynatrace-service, use the Helm CLI to delete the release of the service:
helm delete -n keptn dynatrace-service
Note, this command only removes the Dynatrace integration into Keptn. Other components, such as the Dynatrace OneAgent on Kubernetes are unaffected.
To remove Dynatrace monitoring on your Kubernetes cluster, please follow the official Dynatrace documentation on uninstalling OneAgent Operator.
