Hi @aurelien-denis
If you use the taxonomy with multiple values, I believe you can do that too. But please keep in mind that ACF format the taxonomy ID ($post_id) like this: taxonomy-slug_99, where “taxonomy-slug” is the taxonomy slug you have and “99” is the taxonomy ID. This page should give you more idea about it: https://www.advancedcustomfields.com/resources/get-values-from-a-taxonomy-term/.
I hope this helps 🙂
