This is a most excellent place for technology news and articles.
Seriously, this is the way. I did this too in about 15 mins. Also setup a simple rule to allow the vlan to reach my homeserver in a separate vlan specifically on Plex and Jellyfin ports. That's it. They cant phone home. You still enjoy your own media.
Yeah if you setup the firewall correctly you can access the TV but the TV can't access anything it self.
