Why do you wish to stop this? This protocol is part of the way the LANDESK clients operate. Features such as distribution, peer download, XDD (in v2016) rely on this to function.
Multicast with LANDESK does not cross routers if that is what you are concerned about.
You can reduce this traffic by using the system differently but knowing why you want to stop this would help.
