And this is why you never ever use ISP DNS, run DNS over HTTPS in the browser, and always use encrypted networking.
And use VPNs appropriate to the activity, when appropriate.
Oh, and never turn on ISP-supplied WiFi, as that gives them full access to the traffic from every device on your LAN, what physical hardware you own, and even where it is located in your home (and when it leaves and comes back to your home).
