Custom views twig template
For my circumstance i have adopted to use the block_alter hook to define the new suggestion for the template. Since homepage only contains the unique views template and the others wouldn't.

function THEME_theme_suggestions_block_alter(&amp;$suggestions, $variables) {
  $path_check = \Drupal::service('path.matcher');

  if (in_array("block__views", $suggestions) &amp;&amp; $path_check-&gt;isFrontPage() == FALSE ) {
    $suggestions[] = 'block__views__blah__custom';
  }

}
