Need some clarification.
What do you mean by execute? Are you talking about the load script or the just looking at the dashboard?
Are you saying that you want the dashboard to default to a filter value? There may be some extensions you could use to do this. But am not sure.
You possibly could use section access to limit what the user sees when the dashboard opens. But you can't block the dashboard from displaying when they open it.
Please find the attached app. Here you can see the chart only when you have selected the Month1 filter only.
Need to apply this condition in the add-ons.
