For client request body, the only available timeout option is
client_body_timeout, which defines a timeout between two read
operations, but not a total upload time (see
http://nginx.org/r/client_body_timeout for details). It can be
accompanied by limit_conn (http://nginx.org/r/limit_conn) to limit
the total number of connections from each client.

If you want something more sophisticated, an option to consider
might be "proxy_request_buffering off;" and appropriate limits on
the backend side (see https://nginx.org/r/proxy_request_buffering
for details). This might not be a good solution though, since in
most cases keeping connections on nginx side is way cheaper than
passing them to backends.
