In an alerts group, you can disable an alert by a single click.

To disable an alert, in the menu, click Alerts and then in the left pane, click All Alerts. Select the alert name from the data grid, and click Actions > Disable.

The alerts can be disabled by two methods:

Disable Alert in All Policies: You disable the alert for all the objects for all the policies.

Disable Alert in Selected Policies: You disable the alert for the objects having the selected policy. Note that this method will work only for objects with alerts.
