In case you were interested in disabling the browser (no root needed), just run the adb command:
adb shell pm disable-user --user 0 com.android.browser
to re-enable it,
adb shell pm enable com.android.browser
I'm on Linux, so adjust your commands according (should be about the same unless you need a leading ./ )
I'm not sure for the webadb as i've never used that.
This method should also work on just about any android phone.
To get a list of package names (so you know what to type in):
adb shell pm list packages -l and this one will just list what you've disabled:
adb shell pm list packages -d
Of course, with access to the developer options, you can just disable apps via the apps sub-menu
