If you are looking to restrict the users that are allowed to edit StockPack settings, you can update the capability for which the settings page will be loaded.
Here’s a sample code that restricts the StockPack settings page to only users that are allowed to upload files.
<?php
add_filter( 'stockpack_settings_capability', 'stockpack_settings' );
function stockpack_settings( $capability ) {
return 'upload_files';
