I’ve rewritten a little bit to also delete the images from the media library

functions.php

function azrClearButton( $field ) {
		global $post;
		echo '<p style="text-align:right"><a href="#" class="acf-button button button-primary acf-gallery-clear" data-postid="'.$post->ID.'">Delete all Images</a></p>';
	}
	add_action('acf/render_field/type=gallery', 'azrClearButton', 10, 1 );
	
	function azrDeleteImagesFromGallery() {		

		?>
		<script type="text/javascript">
			(function($) {
				var azr_TemplateDir = "<?php bloginfo('template_directory') ?>"
				$('.acf-gallery-clear').click(function() {
					console.log('test');
					var postid = $(this).data('postid');
					$.ajax({ 
					    type: 'post', 
					    url: azr_TemplateDir+'/ajax/delete-gallery.ajax.php',
					    data: {'postid': postid}, 
					    dataType: 'json',
						success: function (data) { 
							location.reload();
						}
					});
				});
			
			})(jQuery);	
		</script>
		<?php
	}
	add_action('acf/input/admin_footer', 'azrDeleteImagesFromGallery');

AJAX FILE

require('../../../../wp-load.php');
global $post;
$postid = $_POST['postid'];
$args = array(
	'post_type' => 'attachment',
	'posts_per_page' => -1,
	'post_status' => 'any',
	'post_parent' => $postid
); 
$attachments = get_posts($args);
foreach($attachments as $attachment) :
	wp_delete_attachment($attachment->ID, true );
endforeach;
