Late to the conversation but I wanted to switch the DNS for parents-in-law and found that Comcast has DNS settings locked down (not user changeable) on their router. Since they're also using VoIP and cable from Comcast, I didn't go any further. I wanted to switch the DNS to AdGuard because my mother-in-law had a JavaScript pop-up that convinced her to call "Microsoft". I put uBlock Origin on Chrome and Edge. Users can set the DNS setting on their devices to use something else but I bet it's a tiny fraction that do. As somebody who worked at an ISP, I can sympathize a little bit with not wanting customers to f*ck up their DNS.
