Thanks John,it worked like a charm – I’ve created a multi-select field called “acf-user-schools” and added this:

function acf_load_user_school_field_choices( $field ) {
	
    // reset choices
    $field['choices'] = array();
    
	
               // Get all the schools hierarchy ( Country -> District -> School )
	$schools  = getTaxonomyHierarchy( SCHOOLS_TAXONOMY );
	
	// Get the children (all the districits) of USA
	$schools  = $schools [ USA ]->children;
	
	if ( !empty( $schools  ) AND !is_wp_error( $schools  ) ) 
	{
		foreach( $schools as $district ) 
		{  
			$field['choices'][ $district->term_id ] = $district->name;
		}
	}

    return $field;
    
}
add_filter('acf/load_field/name=acf-user-schools', 'acf_load_user_school_field_choices');

Needed this today, and found the solution.

Here it is in case someone needs it:

function limit_cat_post_relationships( $title, $post3, $field, $post_id  )
{
    /* Because this is proccesd as an AJAX request
     * we can get the referer, and extract the tag_ID from there
     */
    
    $url     = wp_get_referer();
    $parts   = parse_url($url);
    parse_str($parts['query'], $query);

    $title['tax_query'][0]['terms'][0] = $query['tag_ID']; 
    return $title;
}
add_filter('acf/fields/relationship/query/name=ibm_topic_feat_posts', 'limit_cat_post_relationships', 10, 3);
