Change config setting \"Allow users to mount external storage\" to disabled in \"Administration\" > \"External storage\" settings `…/index.php/settings/admin/externalstorages`. Change config setting to disallow users to create external storages in \"Administration\" > \"External storage\" settings `…/index.php/settings/admin/externalstorages` with the types FTP, Nextcloud, SFTP, and/or WebDAV.",
