There is no rooting of Windows Phones. That's an Android thing.Unfortunately, unless you can root a device, and install ad blocking apps, or you can get ABP and change the ports etc, you can't, unless you support the devs and buy the app.
Edge can't have ad blocks (yet) because it doesn't have the facility for extensions. Chrome on the other hand, does, and seems to actively promote ad block or ad block plus. They even have an ad block browser listed in store.
