NVMe slot in Inspiron 15 500 series - 5570?

I've just purchased an Inspiron 15 5000 series 5570 laptop with the Intel(R) Core(TM) i7-8550U Processor and Dual drives with 128GB Solid State Drive+ 1TB 5400 rpm Hard Drive. I need to know if this has an M.2 slot compatible with NVMe (PCIe 3.0 x4) as I'd like to put in a Samsung EVO 960 NVMe M.2 SSD.

Is the 128GB SSD that comes with this a SATA drive? 

I've seen that some Inspiron 15 5000s that come with the i7-7700HQ processor come with 512GB PCIe NVMe M.2 Solid State Drives. Does this use a different motherboard?

Thanks!
