Is it possible to disable the broadband in HDMI?

I want to be sure my TVs are not spying on me, so I want to disable any possible internet connectivity via the HDMI connection (unless I need to do something else). All I know is the televisions can’t be trusted to stay offline. I have a GeForce RTX 4060 DUAL EVO OC Edition card, utilizing the HDMI out, plus the displayport via a displayport to HDMI cable.
