First of all, just because you are not using it doesn't mean that other people aren't. To many people, RealTek Audio is a crucial part of their overall solution.
Secondly, RealTek Audio will only cause problems, such as what you described, if you do something to cause it -- like setting a default audio device, which effectively blocks Intel Display Audio from activating support for a newly-enumerated display device that (also) supports audio output.
Bottom line, no, this won't be happening.
P.S. While I am at it, watch your language. I suggest that you re-read the /docs/DOC-111979 Intel Communities House Rules. This will be your only warning. Repeat this behaviour and your account will be suspended.
