hi

it is stated exactly:

https://support.hp.com/my-en/document/c08326025

Internal Storage

1 TB Intel® PCIe® NVMe™ M.2 SSD

Wireless

Realtek Wi-Fi 6 (2x2) and Bluetooth® 5.2 combo (Supporting Gigabit data rate)

3 M.2 (2 for SSD, 1 for WLAN)

https://support.hp.com/my-en/document/c08138465

• Three M.2 expansion slots:
  • One M.2 socket 1, Key A
  • Two M.2 socket 3, Key M (one for SSD card PCIe Gen 3.0 x4)

therefore, an m2 lan port already occupied
and an m2 ssd port already occupied, there must be one free m2 ssd slot

an m2 ssd, visible ..
the second, can be hidden by the graphics card
