Custom Gesture Sensor?

Hello I’m designing a pcb for this project
and I was wondering if it would be possible to add this to the pcb design into my unit and get the parts from digikey for the unit anyone out there that has experience with this? This unit has a microcontroller how would I go about flashing the unit ?

digikey sells the unit too but I want to modified the layout not of the sensor but of the pcb unit.
