Use DSP mixer for UR-RT4 instead of hardware integration with Cubase

how can I use DSP mixer for UR-RT4 instead of hardware integration when Cubase 12 ?

Computer I’m using: MacBook with M1 chip, OS: Monterey

Until I know, the dsp mixer gets deactivated when you open Cubase. I am not sure if it is possible to avoid that.

Thanks for the answer.
That’s very unfortunate, because the hardware integration in Cubase is extremely inconvenient to use.
