This Can be very easy to repair if it was not broken and impossible if the motherboard is broken : 1.Parts inside any smartphone or tablet are connected by a lego style electrical connectors they can get unplugged easily by a drop 2.Motherboard is broken, sorry but you need to replace the motherboard or buy a new device
well the short answer is No , this tablet latest update is Android 7.0 and Android 8 is 1 year old so if Nvidia wanted to upgrade it to Android 8 they would do it along time ago and do not root your device in order to upgrade it, it is very danger
