Physically disabling WAN can be a workaround, assuming is can be done and reverse without damage. But it’s not a good solution.
Manufacturers have ways to degrade experience/features when the owner physically disable WAN: deny features and security updates (by doing OTA updates only), drag their feet or void warranty if WAN is disabled, design some features to be unnecessarily dependant on some cloud/online services (eg navigation, media features, …).
They cannot void your warranty over that, maybe for the computer you modified but the Magnuson Moss warranty act means they have to honor the warranty unless they can prove your modifications caused the damage.
Also, who cares if it gets updates? It will continue to work as it did from the factory indefinitely. Security updates aren’t necessary if the car isn’t connected to the internet and those updates cant change how the immobilizer/keys work anyways.
