By definition, all windows 11 compatible computers will have DCH drivers which has its audio configuration done via an app downloaded from Microsoft Store.
If your Realtek audio console app (or HP audio app or Dell audio app or Waves audio app) doesn't have EQ, it means that your specific computer model has a premium audio package (such as DTS or Dolby or Nahimic) and your EQ is going to be in the premium audio app.
If the premium audio app doesn't have the traditional 10 band EQ, it means that your computer maker decides not to give you a traditional 10 band EQ. Instead it gives you some smart EQ pre-sets. So when you pick the movie pre-set, it automatically EQ your audio to enhance movie dialogs. When you pick the gaming pre-set, it automatically EQ your audio to enhance explosions.
