The trick is to not buy a "TV".
Get a really big computer monitor/screen, and put it where you'd normally put your TV.

In my case I compromised on needing 4k, and got an lg 65 inch with only HDMI.
You should update the TV when you first unbox it (ideally via ethernet) and then disconnect it. If you don't like Apple TV then your streaming box of choice.
Can you update via USB? I know my (couple years old now) Samsung TVs have firmware downloads available so you don't even need to connect the TV to anything.
I'll echo the Apple TV + Sony TV combo. It's very solid.
You also need to wipe the storage cache for the launcher app after disconnecting to get rid of the junky ads that get downloaded.
