How to prevent the web server from reporting the size of the transferred file?

Question

Nginx

Hello, friends.
You need to somehow prevent the web server from telling the client the size of the transferred file. The web server is not critical, it is necessary for QA to test the crawler functionality.
Tell me, what are the ways?
I tried to cut out the headers, for example - Content-Length - does not work.
