Hi:

The service manual indicates the notebook comes configured with two M.2 NVMe slots.

Maintenance and Service Guide (hp.com)

See chapter 1.

Primary storage M.2 solid-state drive (PCIe®-4 × 4, 2280, non-volatile memory express (NVMe®), three-layer cell (TLC)
2 TB
1 TB
2 × 512 GB
512 GB

Then if you look through chapter 6, you will see motherboard illustrations showing the location of two SSD's, one below each fan.

Last but not least, is the service teardown video which shows the location of the two M.2 slots.
