oops forgot to mention. If you have access to your themes functions.php file the above code will go in there. ??

I came across this upon install too, I use Advanced Custom Fields and it too has a native ‘Duplicate’ action. I was able to exclude the Post Duplicator buttons/link by doing the following.

function excludeDuplicatorAction($actions, $post){
	
	$postType = get_post_type();
	if(in_array($postType , array('acf-field-group'))):
		if(isset($actions['duplicate_post'])):
			unset($actions['duplicate_post']);
		endif;
	endif;

	return $actions;
}
add_filter( 'post_row_actions', 'excludeDuplicatorAction', 11, 2 );
add_filter( 'page_row_actions', 'excludeDuplicatorAction', 11, 2 );	

add_action('pre_get_posts' , function(){
	global $post;
	$postType = get_post_type($post);
	if(in_array($postType , array('acf-field-group'))):
		remove_action('post_submitbox_misc_actions' , 'mtphr_post_duplicator_submitbox');
	endif;

},10);
