I've actually been researching this a little bit more using some of the test sets that I have, and it seems that there might be a way to disable some of these features through the service menu. If you enable the service mode / service menu of the set: https://factory-reset.com/wiki/Samsung_Service_Menu https://factory-reset.com/wiki/Samsung_Service_Menu - then navigate to the "Control" sub menu, disable the following settings: Voice Recognition OFF, Network Support NONE, BT Support OFF, Samsung Smart Control OFF With the "Network Support" in particular it seems to disable all internet related settings on the TV. It seems that in some cases this is in the "extended service menu" for which you will need a special remote to access.
