This patch allows to disable the CollapsibleVector feature for anonymous users by adding the following line in your LocalSettings.php:

$wgCollapsibleVectorFeatures['customSettings']['anonymous'] = false;

Unfortunately the embedded option $wgCollapsibleVectorFeatures['collapsiblenav']['global'] = false; doesn't help in this case. The logged in users are still able to enable the feature via their preferences.

Here is how to apply the patch:

cd $IP/extensions/CollapsibleVector      # $IP is the MediaWiki Document Root directory
sudo patch < <(sudo curl -s https://gist.githubusercontent.com/pa4080/0e7770dfb497f6ed543c8be8110c0b66/raw/c95cd17d6be0f0f6c9b5019742b6fb0b16742b41/CollapsibleVectorHooks.patch)
