Put it in your functions.php file

// this adds a filter for the field that you want
// to dynamically set the label for
// it can be used in several ways
// https://www.advancedcustomfields.com/resources/acfload_field/
add_filter('acf/load_field/key=field_0123456789abc', 'set_my_field_label');

// this is the function that is called for the filter
function set_my_field_label($field) {
  // get the value from the field you want to use for the label
  $label = get_field('field_label_option', 'option');
  if ($label) {
    // if the option is set then change the field label
    // almost any field argument can be changed dyamically
    $field['label'] = $label;
  }
  return $field;
}
