How to remove slider snow effect

Hello,
The new version of enigma-parallax comes with a “snow effect” on the slider.
I need to remove that effect.
After some investigation, I came out with the following solution:
edit customizer.php and remove (or comment out) the following line:
wp_enqueue_script('snow', get_template_directory_uri() .'/js/snowstorm.js');
Is it the correct way to do it?
I am asking because this has to be done at parent-them level, duplicating customizer.php in any child theme directory, and modify it there, has no effect at all.
Thanks for your attention.
