Is it possible to close a page in meta robots if it is closed in robots.txt?

Question

robots.txt

Good day everyone. I have a site on which I need to block pages from indexing with the site.com/ ru attribute . This "ru" tag is indicated in the robots file, but not all pages have fallen out of the index, in order to speed up the process, you can point meta robots on the pages. Actually, the question is: is such an option possible? I heard that if you register tags here and there, then the robot will not perceive any actions.
