Smart TV - firewall so it can only access google store and netflix? (alien.top)

I have a Hisense TV. I was wondering if there's an easy way to firewall their TV so that it only has access to Google Store and Netflix? Make it so the TV can't reach anything else?

I don't currently have any firewall. I have ddwrt as my main router. I can whip up a pihole if needed.

I don't fully understand why you are concerned about what the TV can access on WAN, and not about what the TV can access on LAN? Put it on its own subnet if you're worried about it sending information back about other devices on your network.

every device should only have the access it needs. On trust and untrusted. It’s prudent to make sure a chinesium Roku TV can’t phone home to its manufacturer and can only talk to Roku and Netflix.

There’s a shitton of data a TV could send back home without access to the rest of the network. I mean, many tvs now have microphones.
