Apply change to Schema Markup

Hi, how can I effectively change my article Schema from:

itemtype="https://schema.org/BlogPosting"

to

itemtype="https://schema.org/BlogPosting" itemid="[[CURRENT_LINK]]#richSnippet"

I managed to do it with this function and the following code in my function.php:

add_filter('final_output', function($output) {
    $link = get_permalink();
    $itemid='itemtype="https://schema.org/BlogPosting" itemid="'.$link.'#richSnippet"';
    return str_replace('itemtype="https://schema.org/BlogPosting"', $itemid, $output);
});

It did work, but ended up breaking my pages cache. Any idea of how can I do that in other way?
