Just as a tip, I found out is also possible to use this as a workaround within your custom javascript (should be placed within a jQuery document ready block):

    var deviceAgent = navigator.userAgent.toLowerCase(),
         agentID = deviceAgent.match(/(windows phone|iemobile)/);

    if(agentID) {
        $(".av-parallax-inner").unwrap();
    }  

Tested on lumia 640, seems to work. It removes the parallax element but keeps the image.

In Addition to Elliots solution, there is an easy way to remove it programmaticaly (thereby really removing a shortcode).

This example removes the button shortcode:

 function remove_shortcodes() {
/**
 * Array of shortcodes you want to remove
 * The values of this array should match the shortcode under which the elements are registered
 * Usually, you can find them in your shortcode files under $this->config['shortcode'].
 */
$shortcodes = array('av_button');

/**
 * Accepts an array of shortcodes and whether to remove these shortcodes (true) or not (false)
 */
if( class_exists('ShortcodeHelper') ) {
  ShortcodeHelper::allowed_shortcodes($shortcodes, true); 
}
}
add_action('init', 'remove_shortcodes');

However, this does not work in all contexts, so make sure to hook the function on init (or later)
