How to set up a 404 error output through htaccess?

Question

Hello, I need expert help. There is a .htaccess file, I want to use it to configure the output of the 404 code for pages that do not exist.
Example pages:
https://zctc.ru/addadsasdas/
https://zctc.ru/12311454141
Now it just gives 200 code and opens the main page

htaccess file content

AddDefaultCharset UTF-8
ErrorDocument 404 /sections/404
