In order to support CMAF and Low latency for HLS streaming through Nginx, it is required change in content header.

Instead of "Content-Length" in Header , expected value by player is "Transfer-Encoding : chunked" so that for a 6 sec chunk of media segment player will start streaming fetching data in 200 msec part wise and thus streaming will have low latency . This is supported by HTTP 1.1

Tried below parameter to enable same in Nginx Configuration
chunked_transfer_encoding on;

But its not adding the same in header.

Please suggest better way to do it.
