How can I enable/disable PHP-FPM by default through WHM?

Question

Is there a way to enable/disable PHP-FPM by default for newly created accounts?

Answer

Of course! Using root WHM -> MultiPHP Manager, toggle the selector under "System PHP-FPM" to the desired setting. If enabled, this will make it so that any newly created accounts will be using PHP-FPM. You can select the specific PHP version used just above this, under System PHP Version.
