Notebook Hardware and Upgrade Questions

Hello. My question is regarding the drivers for my SSD. Some info:

• HP Pavilion Laptop 15-cs0059nr (from bottom of device)
• Product Number: 4EY55UA#ABA
• Windows 10 Pro 64-bit Version: 18362.418
• Bitlocker full-disk encryption activated
• recently updated BIOS firmware (F.19)
• recently updated chipset driver (Intel(R) 6th Generation Core Processor Family Platform I/O SATA AHCI Controller. 17.2.8.1029)
• Possibly relevant info from Device Manager
  • Device Manager / Disk drives / SK hynix BC501 ...(long string of letters and numbers)
  • Device Manager / Storage Controllers / Microsoft Storage Spaces Controller
  • Device Manager / Storage Controllers / Standard NVM Express Controller
  • Device Manager / IDE ATA/ATAPI controllers /
    • Intel(R) 6th Generation Core Processor Family Platform I/O SATA AHCI Controller

Recently, an update for Intel Rapid Storage Technology appeared in my HP Support Assistant. I downloaded it and installed it. Nothing strange happened during the install, but afterwords Intel RST was nowhere to be found on my PC (now that I mention it, I don't think it was installed before the download either). I thought it might have something to do with outdated firmware or chipset drivers on my PC so I updated both of those. Then, I tried installing Intel RST from the HP drivers site for my laptop. I was able to install it, but the only interface it connected with was an empty SATA port (I think my laptop's SSD is NVMe). The HP drivers page had a few different versions of the Intel RST drivers. I tried all of them with Kaby Lake in the title but got the same outcome.

I just want to make sure I'm not missing out on faster speeds from my SSD because something failed to install. I appreciate any help you can give. Thanks!
