XPS 8930, extend SSD to HDD?

Hello!

I'm in the process of setting up my new 8930 and it includes a M.2 256GB PCIe x4 SSD + 2TB 7200 rpm Hard Drive. I'm not sure how this works as I've never had one like this before.  There is only one drive so I assume its partitioned? I use my desktop for a lot of large files I work with and the C drive is already full. Is there a way to  extend it into part of the 2TB area?

Thanks!
