There is no documentation about how to turn off daily cap on Application Insights resource even when it is backed by Log Analytics workspace.

    Set the cap to 99999 to make it appear "Off" in Azure portal. But the value is not effective. Effective value is still 1,000 GB. Practically, setting value upto 3000 in ARM/Bicep template takes effect.

    
resource appInsights 'Microsoft.Insights/components@2020-02-02' = {
  name: name
  location: resourceGroup().location
  tags: enrichedTags
  kind: 'web'
  properties: {
    Application_Type: 'web'
    IngestionMode: 'LogAnalytics'
    WorkspaceResourceId: '<log analytics workspace resource id>'
  }
}

resource appInsightsPricingPlan 'microsoft.insights/components/pricingPlans@2017-10-01' = {
  parent: appInsights
  name: 'current'
  properties: {
    // Set a very high cap to avoid hitting it during normal operation. This is closest way to achieve equivalent of no daily cap.
    cap: 99999
    planType: 'Basic'
    stopSendNotificationWhenHitCap: false
  }
}

    I'm not aware of the way of turning off or configuring the daily cap for an Application Insights resource natively through a Bicep template property. While the Microsoft.Insights/components resource exists, it does not offer a direct property for managing the daily volume cap.

    For modern workspace-based Application Insights, you can manage the ingestion limit at the linked Log Analytics Workspace level. To ensure there is no active cap on the workspace, set the dailyQuotaGb property to -1 within the workspaceCapping block of the Microsoft.OperationalInsights/workspaces resource. By default, Log Analytics does not enable a daily cap unless explicitly configured. 

    resource logAnalyticsWorkspace 'Microsoft.OperationalInsights/workspaces@2021-06-01' = {
  name: 'my-workspace'
  location: resourceGroup().location
  properties: {
    workspaceCapping: {
      dailyQuotaGb: -1
    }
  }
}

    If you need to manage the cap for a specific Application Insights component or want to ensure the component-level cap is disabled, use a PowerShell script. The Set-AzApplicationInsightsDailyCap command can be used in a deployment script or CI/CD pipeline to automate this.

    Set-AzApplicationInsightsDailyCap -ResourceGroupName "my-rg" -Name "my-app-insights" -DailyCapGB 1000 -DisableNotificationWhenHitCap

    For workspace-based resources, be aware that the effective limit is the lower of the two caps if both are set on the Application Insights resource and the Log Analytics Workspace. If the cap is reached at either level, data ingestion will stop until the next reset period. '
