In ACF pro you can now use term meta queries, basically the same as meta_query for posts in the get_terms() arguments. https://developer.wordpress.org/reference/functions/get_terms/, but the new WP documentation sucks. See the meta_query section of WP_Query, it should be set up the same way https://codex.wordpress.org/Class_Reference/WP_Query#Custom_Field_Parameters. I really hope that the people doing the new documentation put a little more effort into it when they redo this page or we’re all screwed.
