The code below goes in something like https://wordpress.org/plugins/code-snippets/ or your theme's functions.php file:
function soflyy_dequeue_agile_locator_script() {
if(class_exists ('AgileStoreLocator')){
$core = new AgileStoreLocator();
$name = $core->get_AgileStoreLocator() . '-lib';
wp_dequeue_script( $name );
}}
if($_GET['page'] == 'pmxe-admin-export' || $_GET['page'] == 'pmxi-admin-import'){
add_action( 'wp_print_scripts', 'soflyy_dequeue_agile_locator_script', 100 );
}
