QC as an interface Cut / Reduce monitoring volume without impacting wet signal

Hello,

I’d like to use my QC as an interface, i plugged the outputs directly in my monitors and the usb port in my PC. Is it possible to reduce or mute the volume send by my amp preset to the monitor without impacting the wet signal (usb OUTPUT 3/4) send to my PC or the sound of my pc send to the monitors (usb INPUT 1/2) ?
