Hi @spinner903,
Thanks for the post.
To remove any item from the screen options menu, you would need to hook into the wp admin_head action and add a {display : none} attribute to the div. An example of this code would look like this:
/********************************************
***** Disable option
********************************************/
add_action( 'admin_head', 'remove_wordpress_cfields' );
function remove_wordpress_cfields() {
echo '<style>#postcustom { display: none; }</style>';
echo '<style>label[for=postcustom-hide] { display: none; }</style>';
}
