CHUWI RZBOX compatability

Can someone please tell me:

  1. Is Transcend 32Gb 1 X 32Gb Ddr4 3200Mhz Sodimm System Memory compatible with the CHUWI RZBOX AMD RYZEN 9 4900H | Windows 10 | DDR 16GB+SSD 512GB.
  2. Is WD Blue SN550 1TB NVME M.2 2280 PCIe Gen3 SSD is compatible with the CHUWI RZBOX AMD RYZEN 9 4900H
  3. Can you mix a 16gb of ram module with a 32gb module or do they need to be of the same value?

The RZBOX can support all of these issues!
