You can absolutely have the revanced app take the place of the stock YouTube app. It takes about ten minutes to uninstall the official YouTube client on unrooted devices utilizing standard adb commands. No computer or other devices is needed. It can all be done on the phone itself with USB debugging and LADB. There are plenty of guides online detailing how to uninstall any app, even system apps via these steps. Also, once it's uninstalled, then patch the YouTube app with revanced manager and it will automatically have the same icon and app name as the official YT app by using the default patch settings. Lastly, go into the default app settings for "Open by default" settings section of your newly patched YT client and toggle "Open supported links" to on. Then below that check all four boxes for each type of YouTube URL link. After these steps, the patched YT client will behave exactly as the stock YT app. Links will open in the patched app and you'll never encounter all the garbage and smut that comes with th official YT client. Also, since this uninstalled the official YT app, there's no need to worry about the stock app being automatically reinstalled over time via Play Store updates. The official app will only reappear if manually re-installed by the user.
