i got a good 55in LG oled screen, connected it to wifi and added a firewall rule to block its access to the internet because i hate how lg forces ads

i negated some of the privacy gains by having my “OS” be an apple TV that has internet access but im willing to live with it, since it allows easy remote access to my home assistant through HomeKit, plus the interface is nice and I have RetroArch installed on it, so yeah

You can replicate the same thing but switch the apple TV for a more private and adequate device for your needs
