determine products visible and not visible in custom product loop

Good day! We use the free version of the plugin on our website, we also looked at the paid version (what is included in it) but did not find one important function there – to determine products visible and not visible in custom product loop (like custom search page or custom category loop page making by WP_query). Question to you – what is the opportunity to determine whether they are visible or not anywhere on the site? thank
