Can an iPhone 11 got on Fire be recovered?

Yesterday my iPhone 11 caught on Fire caused by a fault Amazon battery, surprisingly the frame where the battery was located is melted and full of ash, but the cameras and the motherboard have no sign of damage or ash on them, only a part next to the taptic engine which I have no idea what it is and burnt (the part of the charger is perfectly intact), there were important things in that phone, is there any way to test if the motherboard works before taking spare parts unnecessarily?p.s. the phone was open and without a screen, it had recently broken and I was waiting for the replacement to arrive, perhaps this is why the motherboard was not burnt and perhaps recoverable in some way
