Setting no index directive

I am looking for an experienced SEO. Who knows how to set no index directive on certain pages. You can prevent a page from appearing in Google Search by including a noindex meta tag in the page's HTML code, or by returning a 'noindex' header in the HTTP request. When Googlebot next crawls that page and see the tag or header, Googlebot will drop that page entirely from Google Search results, regardless of whether other sites link to it. For this work is requested a person who is working very carefully. Website in Laravel and in German. The no index directive should stop links from an internal search functionality and a booking process. Solution of [login to view URL] already implemented but not search engine friendly. Please only bid in case you are experienced in setting of no index directive on websites and with a language understanding that you are able to set correct tags.
