Yes.

I am not sure why you would do that; or what benefit it will give you;
but that's ok. I do not need to understand that part.


In nginx, a request in handled in a location.

So you want one location that will handle playlist.m3u8 requests and
does the secure_link thing; and a separate location that will handle
all of the other /hls/ requests.

I think you want to proxy_pass all of the requests, so you need proxy_pass
in both locations.

I think you want lots of common config -- add_header, proxy_hide_header --
so it is probably simplest to use nested locations to allow inheritance
rather than duplication.

For example (untested):

location /hls/ {

# all of the common config goes here

proxy_pass http://s3test.s3.amazonaws.com;

location ~ /playlist\.m3u8$ {
secure_link $arg_md5,$arg_expires;
secure_link_md5 "enigma$hls_uri$secure_link_expires";

if ($secure_link = "") { return 403; }
if ($secure_link = "0") { return 410; }
proxy_pass http://s3test.s3.amazonaws.com;
}

}

Adjust to fit the rest of your requirements.

Good luck with it,
