You need to use the Qobuz app in order to enable exclusive mode for Qobuz (the dedicated app should have this as an option). You shouldn't try doing this through Media Center and its embedded Edge/Chromium browsers as web browsers (including the embedded ones) don't support exclusive mode audio output and will always resample through the system mixer before being sent for output via the WDM driver. Same applies to Tidal too in this regard. You have to use the dedicated app instead of doing it from a web browser.
One thing to consider and note is if you try to playback 24-bit/192 kHz content with Qobuz/Tidal apps with the WDM driver, there likely will be issues with stuttering and gaps during playback, it's a known issue with no workaround or fix (other than disabling exclusive mode in Qobuz/Tidal, which it then goes through the system mixer).
