We can achieve this by right-clicking on the Gateway and click on Snooze.
Please note that upon snoozing the Gateway, all actions are cancelled. This means that the action will not be fired even after unsnoozing. The only time it will fire again is if there is a change in state/severity.
If you want to change this behavior, you can enable the option called Queue until unrestricted in the Restrictions section of the Action Advanced Tab.
