Disable all in-app browsing while keeping Chrome as default browser In previous versions of Android, in-app browsing was facilitated using WebView (1). Disabling in-app browsing system-wide could be achieved by uninstalling the WebView app (2).

Recently, an in-app version of Chrome, called Custom Tabs, took over the WebView app (3, 4). This meant the previous trick no longer worked.

How to disable in-app browsing has already been discussed previously (5). However, the answers included uninstalling Chrome and, thereby, uninstalling Custom Tabs.

Is there a way to keep Chrome as the default browser, while also disabling in-app browsing? Clicking on links in certain apps would, then, result in the full Chrome app opening and rendering the webpage.
You need to know this before disabling all in-app browsing,
In-app browsing is a required component by built-in requirements in order for web functions to render properly, as described by Google:
Android WebView is a system component powered by Chrome that allows Android apps to display web content. This component is pre-installed on your device and should be kept up to date to ensure you have the latest security updates and other bug fixes.
So there may be a chance that if you disabled in-app browsing and the Android System WebView, while Chrome as the default web browser, some web components may start failing to function properly.
