Has anyone got this working in Yosemite or El Capitan yet through
profile manager? I'm using Profile Manager not Jamf and i've tried

A good way of greying out the flash menu all together in system
preferences would be:Go to profile manager on your apple server - Device
Group-settings-OSX-restrictions-preferences Click "enable selected
items" and only click the boxes for the items ...
