Hi:
The 128 GB M.2 drive you have in there now is SATA.
You can tell by the fact that it has two notches and by the Samsung part number of the drive.
Samsung MZNLN128HAHQ-000H1 - 128GB M.2 2280 SATA III NGFF Solid State SSD (cpumedics.com)
Below is the link to the service manual for your notebook.
Maintenance and Service Guide HP 15 Laptop PC
Chapter 1 has the supported drive types.
According to chapter 1, your notebook's M.2 slot supports both SATA and NVMe SSD"s. so you can install either type.
NVMe M.2 SSD"s provide faster read/write speeds than SATA ones do, but they run hotter due to the faster read/write speeds.
Since the service manual indicates that NVMe drives are supported, the Kingston A2000 should work for you.
