Dequeue script to prevent javascript event conflict on wordpress child theme

First of all, to resolve the javascript conflict I’ve set up a simple tl_custom.js under my theme js/ folder, with the following code

jQuery(document).ready(function($) {
    //  Remove handler set by themes/Divi/js/custom.js at line 2642
    $( 'a[href*=#]:not([href=#])' ).off();
});

Then I add the script with the following code in functions.php

function tl_custom_scripts() {
    if ( ! is_admin() ) {
        $scriptsrc = get_stylesheet_directory_uri() . '/js/';
        wp_register_script( 'tl_custom', $scriptsrc . 'tl_custom.js', '', '', true );
        wp_enqueue_script( 'tl_custom' );
    }
}
add_action( 'wp_enqueue_scripts', 'tl_custom_scripts', 20 );

The main problem is that the parent theme register custom.js in the footer, so I had to set the wp_register_script last parameter to true and then set add_action priority to 20.
