As already mentioned by Robert, proxy_set_header with an empty
value will prevent a header from being sent to upstream servers.

Note well that when caching is enabled, nginx will not send the
Range header to upstream servers. It is removed automatically
along with several other headers, see
http://nginx.org/r/proxy_set_header:

: If caching is enabled, the header fields “If-Modified-Since”,
: “If-Unmodified-Since”, “If-None-Match”, “If-Match”, “Range”, and
: “If-Range” from the original request are not passed to the proxied
: server.

That is, there is no need to do anything special with the Range
header.
