As you maintain full control of your server you are free to re-enable some or all of these functions. You can do this by modifying the disable_functions directive in your /etc/php/{PHP_VERSION}/fpm/php.ini file. For more information on how to update PHP settings, check out our Changing PHP Settings doc. Be aware that the disable_functions directive cannot be modified on a per-site basis and must be set in your php.ini file.
