Can I upgrade my HP Pavilion x360 Convertible 14m-cd0xxx to M.2?

[OJMG93]

Hello guys, I come to you with an idea I have.

I recently upgraded the Ram on my HP Pavilion x360 Convertible 14m-cd0xxx from 8Gb to 16Gb and switched the HDD to an SDD, but in the process, I saw that the motherboard seems to have a port for an M.2 drive right by the Hard Drive bay, attached at the end I'm posting a picture of the port and seems to be long enough for a 2280 M.2.  Now I have two questions about this:

Could I install an M.2 on this port and still have the possibility to use my hard drive?  I ask this because I know some motherboard/CPU combinations don't have support to that many SATA lanes and if you, for example, install an M.2 then the SATA port for the hard drive gets disabled.  My idea would be to install an M.2 with around 256Gb of capacity to use as a boot drive and keep the  SSD for mass storage since I already have it.

The other question is if what I wrote above is possible, which M.2 would I require?  I assume my motherboard won't support NVME or PCIe so I'm guessing maybe a SATA III M.2 would be what I have to use.

Either way, I'm leaving my system specifications below:

-CPU: Intel Core i3-8130U @ 2.2Ghz

-Motherboard: HP 8486 (according to CPU-Z)

I would greatly appreciate any insight you guys may have about this.  Let me know if there's any other information about my system required.

Page 2 of the manual says the series supports

             16-GB, PCIe, Optane, solid-state drive with 1-TB, 5400-rpm hard drive

That indicates you can add M.2 NVMe to your machine using

        https://www.crucial.com/products/ssd/crucial-p2-ssd
  Or similar from reputable vendors.

   But to be sure is to be sure, the following machine supports M.2 SATA SSD

You need to know what is your 14m-cd0xxx  first.

Hello, thank you so much for your help.

I'm sorry you are right I forgot the correct serial number of the computer, it is 14m-cd0001dx.

Would you happen to have information about this model?
