How to specify a timeout for a dav method (PUT)

[GabrielGhe]

I have an Nginx instance that I use as a Bazel cache with the config below. I'd like to set a low (4 second) timeout for the PUT (dav_methods) requests.

The config looks like:

http {
  ...
  # request timed out
  client_body_timeout 2;
  client_header_timeout 2;

  # server will close connection
  keepalive_timeout 5;

  send_timeout 1;

  gzip on;

  server {
    listen 80 default_server;
    server_name _;

    location ~ "<my regex>" {
      root <my dir>;
      dav_methods PUT;
      limit_except PUT GET { deny all; }
      create_full_put_path on;
    }
  }
}

GET methods timeout as expected, PUTS don't.
Any idea how to put a timeout the PUT method?
