Exclude php snippet with script code from running on subpages

Hi,
I’m using this code to run my script only on specific pages based on IDs:

add_action( 'wp_head', function () {
	if ( ! is_page( [ 24738, 24739 ] )) {
		return;
	} ?>
<script> my script </script>
<?php } );

But I realized that it would be better (in my case) to exclude all the subpages of a specific page. I’ll explain myself better.

I want to exclude all these pages: http://www.my-site.com/course/name-of-the-course-1, http://www.my-site.com/course/name-of-the-course-2, etc

In this way there is no need to “update” the snippet with all the new IDs of the pages that I want to exclude..

Tips on how to do it would be really appreciated!
