Adjusting ducking level in AVAudioSession

New on iOS17 we can control the amount of 'other audio' ducking through the AVAudioEngine. Is this also possible on AVAudioSession?

In my app I don't voice input, but I do play voice audio while music from other apps plays in the background. Often the music either drowns to voice, if I use the .mixWithOthers category, or it's not loud enough if I use .duckOthers. It would be awesome to have the level of control that AVAudioEngine has.
