Set custom launcher for Samsung Galaxy Tab

Set custom launcher for Samsung Galaxy Tab

Hi,
I am using MDM Plus for enrollment on some Samsung Galaxy Tabs. I am required to use my own starter / home / launcher application. 
Where can I find setting to configure the custom launcher? 
Kiosk Mode with single app unfortunantelly does not help completly. If I use that, the quick settings are bocked and the user is not able to swipe down to change volume, brightness and so on. 
Best regards
Daniel
