Samsung released WHQL Signed NVMe Drivers a few hours ago...

They are still 2.2, but actually signed now

If you can read the NVME in BIOS, it won't need the Signing like on the G751, because AMI/Aptio will have signed it for you - (as a result of adding it for native support).
There's 3 stages where the driver can get injected - Windows PE (straight after POST/BIOS), then Windows itself, then in Recovery (Winre.wim in Hidden Partition C:\Recovery)
On the newer 960, the controller changed from on board, to another chip - i can't remember what it's called - but it changed where/how Windows sees the drive and it's controller - so the 960s will be OK - but for the older people using the 950 - if Windows tries to load the 2.2 driver - it may cause the Invalid signature.
If you have the 1.4.7 (1.1) driver still in the WinSxS directory - Windows will fall back to that during one of those 3 stages. I had the invalid signature when I purged my windows driver store - some people may experience other faults, or not at all.
The IRQ for the NVME and the SATA in AHCI/RAID should occupy the highest portion of the Negative IRQ (Closest to Zero) Starting at -2. This is where the problem can manifest - where Windows will set a different affinity for one of the drives - and then you'll encounter a BSOD or something
IRQL_NOT_LESS_OR_EQUAL
This is why you can't switch out in BIOS between AHCI or RAID once Windows is Installed. The AHCI on the HM87 is categorised as IDE/SATA ACHI Controller, and the RAID is SCSI SATA RAID Controller.
I had some spare time, so I wiped the default Windows AHCI RAID disks I had, and set them up in Bios as RAID, and I have it working while Samsung Magician is installed.
The drives I had was the stock HGST 1TB 7kRPM - and they have a 60% increase in performance. I would recommend doing a Hardware Raid, if users are going to use a RAID set up - but it would only be worth while - doing so at a New Install - trying to do this conversion on an Installed Online OS, is impossible - well .... (not really I did it just before - but I had to preload and install the IaStorAC.inf, before loading the IaAHCIC.inf in the Windows PE, OS and Recovery) - but I didn't bother with recovering data from the original RAID 0, and just chose to wipe. (I'll link you to the posts with my Bench) https://rog.asus.com/forum/showthread.php?95544-G751JY-Windows-10-1703-Creators-Update-2017-Driver-L...
I haven't heard back from Samsung yet - but I'm assuming that it's not an issue for their future product line - so there's no need for them to Sign the driver for what they would now consider a Legacy device for their NVMe Range.

Yes the only reason for a RAID Array with SSD is like I have on one of my workstation. I have a 500 gb hard drive fail on a highly used data drive. I also had an old Intel 530 240GB SSD and a Samsung 840 256 GB SSD I put them in raid on to create 1 aprox 500 GB drive. I have confindenct that this SSD Array will outlast just about any Spinner.
Our notebooks come in RAID configuration with out any array, were just using intel IRST driver because it's a excellent driver for SSD's Samsung's NVME driver has not been shown to be any better than the IRST with the only difference being access to Samsung magician which is pretty much a useless program not needed for anything.
