Problem:

How to force the Javascript file of the Maps plugin to load at a later time?

Solution:

There is no such an option in Toolset.

You can force Toolset to avoid loading the Map Javascript files by adding the code below:

function my_dequeue_script() {
wp_deregister_script( 'google-maps' );
wp_dequeue_script( 'google-maps' );
}
add_action( 'wp_print_scripts', 'my_dequeue_script', 200 );

After that, you can add the Javascript files below at a later time that you want:

/wp-content/plugins/toolset-maps/resources/js/jquery.geocomplete.min.js
/wp-content/plugins/toolset-maps/resources/js/views_filter_distance_frontend.js
/wp-content/plugins/toolset-maps/resources/js/wpv_addon_maps.js
