Disable the "Do not show me this page again" Option
To disable the ability to toggle the "Do not show me this page again" option on the Reason tab of all restores, create the following registry value on the Veeam Backup Server.
Note: If the Reason tab has already been hidden, this setting will not unhide it; this registry setting only prevents the setting from being modified.
