Is it possible to acheive a button swap?

I have a drum machine and an effects unit… I am wondering if somehow using the soft button and a DCA or something to acheive a ‘seamless’ swap between sending direct audio from the drum machine and then when hitting the button to mute/lower the fader output on the drum machine and also raise the level/unmute on the aux send running to the effects unit?

Currently the only way that I know how to swap between the two is using the faders on the processing page and it’s a bit clunky trying to achieve a “seamless” or “instant” transition between effects and no effects.
