Below is the link to the service manual.

Maintenance and Service Guide HP 15 Laptop PC

Chapter 1 has the supported drive types.

Your notebook does not have any support to install a 2.5" drive or a second M.2 SSD.

If you need more storage, you will have to replace the existing NVMe SSD and install one having a greater storage capacity.
