You could try going to Settings->Touch & Pedal Settings->Pedal Actions and mapping the volume up and volume down buttons to actions that wouldn't interfere with your use of the app. See if this catches the volume presses and stops the OS from pressing them. If there aren't any actions you can use, this at least tells us that there is a mechanism that can be used to stop it from happening. I don't really want to have to add a specific setting to disable OS volume changes, but that may be the cleanest option.
