Hi @trainsrenton
I’m afraid you need to use the wpdb class instead. This page should give you more idea about it: https://www.advancedcustomfields.com/resources/querying-the-database-for-repeater-sub-field-values/. To learn more about wpdb, please check this page: https://codex.wordpress.org/Class_Reference/wpdb.
I hope this helps 🙂
