A:Answer I found a reseller that offers this laptop upgraded with 64GB/2TB (2x32GB, 1x2TB IIRC), though I can't recommend them. I bought from them before buying this one but had to return it because of defective memory. As long as my problem was just a defect and not a symptom of operating out of spec, you can take that as evidence that doubling the RAM is feasible.
This particular configuration uses both slots for RAM (2x16GB) and both slots for SSD (2x1TB). Since you'd be replacing, not adding, you'd be better off starting with a configuration with less storage. I thought that opening it up to upgrade it might void the warranty, but cursory online research suggests otherwise (please double-check). From the outside, it looks like it's meant to be user-serviceable (Phillips screws, not Torx).
