I believe that you are talking about having 2 fields where the second taxonomy field shows results based on the selection in another taxonomy field.

This is not easy and I do not have the details. I can only give you a rough outline.

• You need to add custom JavaScript to ACF.
• You need to use the ACF JS API hook select2_ajax_data to add the value selected in the first field to the AJAX data.
• You need to use the acf/fields/taxonomy/query filter to filter the taxonomy query based on the value from the other field.
