Like smart TVs, the only possible alternative is buying a 10 year old model on the secondhand market. Vehicles without these features have not been produced in a long time
Of course they're not mass-market and will be lacking on some other bullet point features, but if you really care about your TV not turning into an ad billboard in 2 years, they're the way to go.
Or never wire the tv. Thats what I did. Everything runs through my Apple TV (admittedly captured by my years of employment there) but could just as well run through a Kodi instance
