I connected it once, then set it in the router as „enable child protection -> disable internet access“, gave it a static IP address and also blacklisted that address on my pi hole so that DNS won’t work for it. Then I immediately disconnected it. The router recognizes the TV with its MAC address when it gets reconnected and immediately bans internet access when it gets reconnected.
