Hi,
I have a GE65 Raider 9SE laptop with
RTX 2060 6GB and
RAM 2x8GB (16GB) DDR4 - 2667,
1TB M.2/PCIe SSD.
Intel Core i7 - 9750H

My Question is can I upgrade my RAM TO

Crucial 64GB Kit (2 x 32GB) DDR4-2666 SODIMM or
Can I Use
Crucial 64GB Kit (2 x 32GB) DDR4-3200 SODIMM?

and also Can I Upgrade my SSD to Crucial P3 Plus 4TB PCIe M.2 2280 SSD while still keeping my Stock 1TB M.2/PCIe SSD? (So overall 5TB hard disk space)?

Is it also possible to upgrade my VGA and processor?

Can I please get some help please?
Thank You
