How to exclude site category in head meta tag output php file in prestashop?

Question

Prestashop

Tell me, how to exclude the category of a site with a url like sitename.com/blog/page1...99 using php in the file that is responsible for displaying page meta tags in the head? It is necessary that meta tags are not displayed on the pages of this category.
I was recommended this code:

if(parse_url($_SERVER['REQUEST_URI'])['path'] != "/blog"){
// Выводим мета-данные
}

I don't quite understand how to apply it. Where should this code be placed in the file that displays meta tags on pages?

Place the code in the Template and not in the model or controller. Give the template code and we'll see.
