Dequeue Maps Builder JS except certain pages

dequeue.php

<?php

/**
 * Dequeue GMB script for certain pages
 *
 * Hooked to the wp_print_scripts action, with a late priority (100),
 * so that it is after the script was enqueued.
 */
function gmb_dequeue_script() {
	global $post;

    wp_deregister_script( 'google-maps-builder-gmaps' );
    wp_dequeue_script( 'google-maps-builder-gmaps' );
	
	$posts = array(754, 586);
	
	if ( in_array($form_id, $posts) ) {
        wp_register_script( 'google-maps-builder-gmaps' );
        wp_enqueue_script( 'google-maps-builder-gmaps' );
	}
 
}
add_action( 'wp_print_scripts', 'gmb_dequeue_script', 100 );

Tried using this but "$form_id" isn't referenced anywhere and throws an error. It then also didn't like the way the "wp_register_script() was being used saying missing 2nd argument.
