Is it possible to not record user's discord/music while he has our game audio on?

Hey, Is it possible to not record the user’s discord/music while he has our game audio on? Because for some reason, it captures all sounds on the PC.

No, we capture the global system sound, not the game’s specific sound.
One may use a virtual audio device and set the game’s output + Overwolf’s system capture on that device.

You can also set the system capture device via API
