In order to turn off your dashboard and start directly from the main cases page, first you need to open your Dashboard Settings page (You can find more information about dashboard settings here).
From this page, simply check the "Bypass Dashboard and redirect to main Cases page?" checkbox, and click on Save Changes.
This will turn off your Dashboard, and start your access from the Cases page instead.
You can enable the dashboard anytime by unchecking this checkbox.
