The only way that I can think to do this would be to create an acf/update_value filter https://www.advancedcustomfields.com/resources/acf-update_value/ for this field and then add any required term IDs to the value

add_filter('acf/update_value/name=your-field_name', 'force_required_terms', 20, 3);
function force_required_terms($value, $post_id, $field) {
  // required term ID 1234
  if (!in_array(1234, $value)) {
    $value[] = 1234;
  }
  return $value;
}
