According to Specifications-->Compatibility-->Operating System," it comes with Windows 11 Pro, which is NEVER in S mode. If you want S Mode, there are steps that can be taken to emulate it, or you can try reinstalling the OS system.

I checked using Gemini AI, according to which you can go up to 64GB in RAM. Also, even though you didn't ask, I checked for storage update, and Gemini says you can go up to 4TB on the NVMe. Plus, there should be space for a SATA connecting SSD which you can add as well.

My quick quick search told me that the unit USUALLY has 16GB of RAM, so it's probably available, although not necessarily from BB, and almost certainly not at this price.
