I have a Sony too, and it’s a little too chatty for my liking. I blocked port 53 unless it came from my own dns and added the below to my blocklist on a pihole. It’s deeply imperfect but has blocked a lot of their crap. I had to whitelist one Netflix domain.

Edit: I just checked. The Sony TV made 8249 requests in the last 24 hours. I have more locking down to do.
