Is the secondary nvme slot on the HP Envy 2021 actually enabled? I've tried both GEN3 and GEN4 NVMEs and neither were detected in the BIOS or Windows OS. Would like to know if there is a systems limitation or a hardware defect requiring me to return my system to the retailer. Thanks in advance.

Hi,
The notebook has one M2 slot
what do you mean by "secondary"?
What makes you think the slot is not working. Is the drive not seen during installation?

On the 15-ep1000 (322x6AV) there are most certainly two slots. I see the problem the second slot appears to be more for caching than for actual storage expansion. Notice the left slot, "PCIe only SSD1 Optane" from this youtube review video of the model. This was a bit misleading on the microcenter spec sheet as it did call out 2 slots.

I see. The manual listed on the product page is actually the wrong manual (for 17 cg0000), so sorry about that.
Yes, two M2 slots.
When you install an M2 drive in the second slot and go into Disk Management, the drive is not visible. I mean you have initialized the drive.
Regards,

No, unfortunately thats not the case and why I've come here. I pulled the existing 1TB drive in the primary slot and replaced it with a 970 EVO Plus (2TB) and reinstalled Windows 11. I added the factory installed nvme to the secondary slot and its not detected at all by the system as I stated in my original post. If the slot is active at all, there is some sort of whitelist that only allows specifics drives to be added to this slot. I'd like to get clarification from HP on the topic.
