My problem with apps like this is that they force you into using a private DNS/VPN connection. This slows down your network speed and gives the (unknown) DNS provider access to your traffic information. Its kinda the equivalent of using a free VPN, something you should always avoid.
I have installed Shizuku and control apps network access through an app called "App Ops" https://play.google.com/store/apps/details?id=rikka.appops
There is also "System UI Tuner"

And "Canta" which allows you to delete bloatware
