so far yes.

Interestingly I decided to take another crack at this. I put the 980 Pro into the M2M slot and left SATA3 4&5 ports unconnected, AHCI on, CSM & Secure Boot disabled. BIOS saw the new NVMe again. I got excited and did a reboot and the SSD isn’t appearing again.
I’ve decided to just leave the NVMe connected and every now and then I’ll test things out. Will also try to find a custom BIOS to test.

In case anyone is still following this thread….
GOOD NEWS!
I accidentally stumbled upon a setting in BIOS that did the trick: “Intel Platform Trust Technology (PTT)” was set to ‘Enabled’. I didn’t know what it was so I looked in the mobo manual and saw that although it doesn’t explain what its purpose is, it is set to ‘Disabled’ by default. So I disabled it. After a reboot into BIOS, boom! the new NVMe in the M2M slot appears!
I then got back into Windows and the drive is picked up in Disk Management. I named it and assigned a drive letter. I shall be moving the aforementioned Steam games to this SSD.
Overall what a headache. I was seriously pondering of procuring a new mobo/CPU but now (and still sadly) I can hold off on that expense.
Now I’m curious if I should go back and see if any previously revised settings (AHCI, CSM Support, SecureBoot, etc.) should be reverted? Maybe some more experimenting in the next day or so.
And I need to ge search what that PTT is all about.
L8R!

As far as I know, AHCI, CSM Support, and SecureBoot shouldn't impact NVME drive detection.
- AHCI deals with SATA
- CSM deals with older OS where UEFI isn't supported so if you are on Win11 then I would just turn it off and make it stay off unless you installed Windows 11 with it on
- SecureBoot is more or less a Win11 thing

Those were all settings suggested to disable for troubleshooting NVMe detection from various sites posted on the interwebs.
I‘ll likely just leave everything as they are currently set now.
Update:
Ended up turning PTT back on since apparently that is considered TPM 2.0 by Windows. Windows 11 was trying to install 22H2 update and erroring out due to no TPM available. I reluctantly re-enabled it and the new NVMe remained detected which is good.
I’m pretty certain 22H2 was installed long ago but is not showing as listed in the update history. Win 11 Update is also now stating there’s no new updates available after the reboot. Weird.
