It's AI noise cancellation, so you may look for it under ai tweaker. But I doubt it will help even if you find it --- as you are not talking on the mic when you are watching a netflix movie or listening to spotify (so there is nothing to cancel), It may matter if you are talking via discord while playing a game.
Here is Mokichu's take on SS3/DTS (which is the same as me).
Mokichu's driver is UNOFFICIAL. I don't advise people to install it.
I also disagree with Mokichu's installation method as it leaves no driver rollback option (since his method completely deleted your previous driver from your computer). Microsoft designed the official installation method to give you a rollback option, in case the new driver has bugs so you can rollback to the older driver. His method defeats Microsoft's design.
Here is my driver, you won't find anyone on this planet to have a non-Asus branded (Mokichu unofficial driver is 9514) or non-MSI-branded 9514 driver (from MSI Z490-A Pro motherboard has 9514 driver) today.
