How to remove specific meta-tag from header section of page? How to remove specific meta-tag from header section of page ?

I am trying to remove 

&lt;link rel="delete-form-edit" href="/node/11/delete" /&gt;


tag from header section of the page ,but no luck.

As there is no tag as shown above  found on html.html.twig file header section ,its automatically generating.
I think you need hook_page_attachments_alter, which Alter attachments (typically assets) to a page before it is rendered.

 /**
 * Implements hook_page_attachments_alter().
 * @param array $attachments
 */
function my_module_page_attachments_alter(array &amp;$attachments) {
  if (!isset($attachments['#attached']['html_head_link'])) {
    return;
  }
  $unset_html_head_link = [
    'canonical',
    'shortlink',
    'delete-form',
    'edit-form',
    'version-history',
    'revision',
  ];
  foreach ($attachments['#attached']['html_head_link'] as $key =&gt; $value) {
    if (isset($value[0]['rel']) &amp;&amp; in_array($value[0]['rel'], $unset_html_head_link)) {
      unset($attachments['#attached']['html_head_link'][$key]);
    }
  }
}

/**
 * Implements hook_module_implements_alter().
 */
function my_module_module_implements_alter(&amp;$implementations, $hook) {
  if ($hook === 'page_attachments_alter') {
    $group = $implementations['my_module'];
    unset($implementations['my_module']);
    $implementations['my_module'] = $group;
  }
}
