@Maenard11 -- according to the hardware manual: 

  http://h10032.www1.hp.com/ctg/Manual/c06914467.pdf

this computer seems to have:

Storage

● M.2, SATA, solid-state drive
● 512 GB, PCIe, TLC
● 512 GB, PCIe, value
● 256 GB, PCI, value
● 256 GB, PCI, value + 16 GB Optane™ memory module
● 128 GB, SATA-3, TLC

which seems to have provision for both an M.2 stick and a SSD.

Have you searched on YouTube for a "disassembly" or "upgrade" video that shows the insides ?
