On version 4.17.0, Extensions page was added in the Dashboard area of WordPress File Upload plugin.
This page displays all the extensions installed with the plugin.

Administrators can activate/deactivate an extension individually, by pressing the relevant Activate/Deactivate button of that extension.
All extensions are active by default. However, there might be occasions where it is necessary to deactivate one or more, in order to avoid conflicts with other plugins or the theme, or for troubleshooting purposes.
