I applied the FW update per the instructions and it worked fine.  As usual a reboot was required and all is well.
I have a Dell XPS 8930 and the support page shows a "recommended" update for the Samsung PM981a NVMe 2048 GB drive that came in my 8930.  I tried to put a cut and paste description in this post but it kept rejecting it. The update was just released about a month ago.  Have any of you installed this and did you have any problems? BTW this is from the description for this update
Firmware update for PM981a NVMe 2048 GB
