Probably not that easy, probably goes to a board which goes to a chip which goes to an input which controls 23094809 other things and the washer fluid pump. ☹

Depending on how the switch is wired, normally open or normally closed, all you would have to do to defeat the switch is tie the wires on the back of the switch together for a normally open switch, and disconnect one of them for a normally closed switch.
However............ the switch is more than likely not wired to anything other than the car’s computer which monitors the switch for a change of state, from open to momentarily closed, or from closed to momentarily open. So trying to defeat the switch can’t be done since you may just put it into a constant state that you can’t change as you would by pushing the switch. A lot of switches on today’s cars are not wired to anything as in the old days. Pushing a switch or turning a knob is just seen as a state change by the computer and the computer responds by sending out the required signal, voltage, etc.
As an example, on my 2016 Colorado, we use a cell phone blue-toothed to the display panel to display the Google maps screen when we travel someplace that we aren’t too familiar with. When Google maps give a verbal direction, it automatically turns the volume of the radio off until the verbal direction is completed, all without having to touch any of the volume controls. Also, if we have the fan going for defrosting, or getting heat, it is also turned off automatically until the direction is completed, again without manually touching a switch. This is all being done by the computer which is constantly monitoring those switches but reacts to Google maps in the same manner as if a manual switch change was being made. Google maps sends a signal to the computer that tells it to do these things by blue-tooth.
Because the computer is responding to states of change, you can have multiple switches for controlling something without them having to be hardwired together. As another example, I can control all the radio features from multiple switches in multiple locations and from the display buttons as well.

On the 2019 Jeep Cherokee there is an available button to push to deactivate the start stop system, however, it must be pushed each time the engine is started the first time. I only wish that button would permanently deactivate that start stop system. I cannot help but believe that continual cranking of the engine would be detrimental to the starter and the battery. Now just to remember to "push that button".

Any time you come to a complete stop, release the brakes momentarily (and maybe you have to move a bit), come to another complete stop it will then not do another auto-stop until after you have been up to some specific speed (which I can’t quote of the top of my head).
