The code to these TVs is not open source so you have only Samsung to fix it. As to blocking, if you do that then all the smart hub things fail.

My 2014 Smart TV model has automatic firmware updates disabled. This doesn't stop it from checking for updates and prompting me to do it.
Having been burned last time I tried to update it - it rendered the unit unusable - I don't want to update unless I absolutely must.
I also don't want to disable Internet access either.
So my question is how to I stop it from checking for updates or stop prompting me about it? Is there some domain or IP address that I can block at the router?
Thanks.
