How to hide pagination pages from indexing in Bitrix?

Question

1C-Bitrix

The section has a pagination of 5 pages. You need to hide pages 2 to 5 with a meta tag .
<meta name="robots" content="noindex, follow" />

Answer 1

As a result, I wrote in header.php:

$url = 'https://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
if (strpos($url,'emali/?PAGEN_') !== false) {
    $APPLICATION->SetPageProperty("robots", "noindex, nofollow");
}

Because it was necessary to hide pagination pages in a certain section.
If you hide pagination pages from indexing on the entire site:

if ($_GET['PAGEN_1']) {
    $APPLICATION->SetPageProperty("robots", "noindex, nofollow");
}

Answer 2

if (pagination->pageNum!=1) {
$APPLICATION->SetPageProperty("robots", "noindex, nofollow");
}
