This is what worked for filtering inside the Taxonomy Term Editor ( no repeater )

add_filter('acf/fields/post_object/query/name=courses_list', 'filter_by_category');
function filter_by_category( $args, $field, $post_id ) {
     
    // $post_id comes in here as term_# so we need to remove 'term_' to get the term ID
    $prefix = 'term_';
    
    // Also if you are creating a new taxonomy, post_id = 'term_0' so then there's no point in adding a filter
    if ( 'term_0' != $post_id && substr( $post_id, 0, strlen( $prefix )) == $prefix ) {
        // Set $term_id to the ID part of $post_id
        $term_id = substr( $post_id, strlen( $prefix ) );
        
        // And adjust the query to filter by specific taxonomy term
        $args['tax_query'] = array(
            array(
                'taxonomy'  => 'school',
                'field'     => 'term_id',
                'terms'     => array($term_id),
            ),
        );
    }
    return $args;

}
