Enable/ disable „Display author and date information“ per node?
You can override the variable display_submitted in a preprocess hook:

mytheme.theme:

function mytheme_preprocess_node(&amp;$variables) {

  // check if this is the right content type where the field exists
  if ($variables['node']-&gt;getType() != 'article') {
    return;
  }

  // plain field
  if ($variables['node']-&gt;field_where_to_publish-&gt;value == 'public') {
    $variables['display_submitted'] = FALSE;
  }

  // taxonomy field
  $field = $variables['node']-&gt;field_where_to_publish;
  if (!$field-&gt;isEmpty() &amp;&amp; $field-&gt;entity-&gt;label() == 'public') {
    $variables['display_submitted'] = FALSE;
  }

}
