Point Contour boxes to a different wi-fi

Boss bought a home in NOLA that's basically a bomb shelter. Concrete walls inside and out 18-24 inches thick. Installed an independent, enterprise grade Mesh wi-fi 6 system throught home to overcome the limitations posed by normal setup. I want to point his wi-fi connected contour boxes to OUR wi-fi rather than the Cox Panoramic wi-fi system that is basically useless on the floor below. Is this possible? If so how? The devices seem to be locked onto the cox equipment. Thanks in advance,

Jude
