To prevent automatic firmware updates, ads, and any other spying I'm not aware of, I block these in DNS:
*.samsungcloudsolution.com
*.samsungosp.com
*.samsungqbe.com
*.samsungcloud.tv
*.samsungads.com
The first one gets the most hits.
I also don't connect my Samsung displays to Wifi anymore. Unless I notice a problem that I have to search to fix. Then if there's a firmware update that fixes the issues, I'll do it.
NextDNS and ControlD are helpful for blocking this sort if thing, or Pi-Hole if you want to set it up yourself.
My samsung was so noisy that I went to forget the wifi network... but it couldnt. So I ended up blocking its mac at the router. Prior to that it was always the #1 blocked device on my pihole.
