This is a regular request but as we've stated a few dozen times before, HandBrake is a video transcoder. The engine wasn't designed with this in mind and it's not practical to retrofit this in. Sorry. Marking as duplicate, rejected.

I am using Handbrake for years now an always wanted this feature too...
To convert/remove Audio /Subs it is a good idea to have a look at ffmpeg.
To convert DTS Audio in AC3 Audio and remove Subs, you just need a simple CMD:

ffmpeg.exe -i input.mkv -sn -c:v copy -c:a ac3 -b:a 448k output.mkv
