Relevant ARM Template code (we only need the resource object for the above resourceType and apiVersion, but if it's easier you can include the entire template

  "type": "Microsoft.Insights/scheduledQueryRules",
  "apiVersion": "2018-04-16",
  "location": "northeurope",
  "properties": {

      "dataSourceId": "<WORKSPACE_ID>",
      "queryType": "ResultCount"
    },
    "schedule": {
      "frequencyInMinutes": "15",

Expected response (i.e. "I expected no noise since the template has not been modified since the resources were deployed)
No noise after the resource is deployed and the template not changed

Reproduce the Azure CLI 2.8.0 what-if output for the Microsoft.Insights/scheduledQueryRules resource at API version 2018-04-16 using the ARM resource object shown. No repository file or test is named in the issue, so first locate the comparison and noise-suppression path for this resource type; done means an unchanged deployed template is no longer reported as Create.
