Unfortunately DNS based ad-blocking solutions are nowhere near as effective and convenient as an extension like uBO. Even if you have a publicly available DNS based service they will tend to be more lax in order to not break sites which lets many ads through.

I use a combination of PiHole, Firefox+uBO, and VPN + FW rules to stay as much away from ads as possible even when browsing mobile. uBO is the single most convenient and effective measure out of all of them.
