Hi,   i’ve accidentally damaged the flex of the front speaker / illuminator assembly.   so FaceID isn’t working now, couldn’t set ip up, no particular error  message.   Front Camera is working expect the portrait   animoji is working good.   so I assume on of the sensor is affected and my question is simple :   is the FaceID functions will be still available if i replace the full front speaker/sensor module ?   Thanks all.

FaceID depends on the front camera flex being paired with the phone so using another one would disable FaceID. To get FaceID working again you will need to get the screen replaced by apple.
