Enable "highlighted image" on specific Wordpress pages

Question

I used the following command to enable "highlighted images" in my site posts in Wordpress:

// HABILITANDO IMAGENS DESTACADAS EM POSTS
add_theme_support('post-thumbnails', array('post'));

How to enable this function on some specific pages of the site? I don’t want to enable on all pages. Just, for example, on the "About" page and on the "Contact Us" page".

This refinement can only be done with CSS or Javascript.

The action is applied only on the pages wp-admin/post.php and wp-admin/post-new.php.
The global $current_screen has the Post Type information that is being shown.
And the global $post has information about the current post where we check the permalink, p.ex.: http://site.com/contato.

add_action( 'admin_footer-post.php', 'metabox_sopt_279492' );
add_action( 'admin_footer-post-new.php', 'metabox_sopt_279492' );

function metabox_sopt_279492() {
    global $current_screen, $post;
    if ( 'page' != $current_screen->id ) 
        return; 

    $checkpages = array( 'sobre', 'contato' );
    if( in_array( $post->post_name, $checkpages ) )
        return;
    ?>
    <script type="text/javascript">
        jQuery(document).ready( function($) {   
            $('#postimagediv').remove(); 
        });
    </script>
    <?php
}
