Need to create a option for remove html tags from the field values

Can you please be more specific on the usecase. Why should the script tag be removable

You can use hook_module_implements_alter() to ensure your module overrides the schemadotorg_jsonld.

/**
 * Implements hook_module_implements_alter().
 */
function my_module_module_implements_alter(array &$implementations, string $hook): void {
  if ($hook === 'page_attachments_alter') {
    $implementation = $implementations[my_module'];
    unset($implementations[my_module']);
    $implementations['my_module'] = $implementation;
  }
}

@jrockowitz, thank you for your comments. I attempted to remove unwanted HTML tags from the schema values. I had tried step #5 before creating this issue, but it didn't work at that time, possibly due to a typo. However, it's working now, so we can proceed in that manner. Thank you for your excellent support.
