Your dump seems to be bios 1.15 and ME 15.0.23.1706
Dell Bios update 1.15 includes ME fw 15.0.41.2158, but all other updates from 1.11 to at least 1.18 include ME 15.0.35.2039 so they downgraded again after update 1.15!
ME 15.0.23.1706 was last time included in update 1.10, so Intel ME got at least once not updated what raises suspicion that the ME firmware might be corrupted.
Follow this guide to re-initialize the ME firmware:

Regarding NVRAM- seems not to contain machine specific information, padding after NVRAM contains DVAR region which has serial, Windows code, service tag…
So it would be easiest to transfer the empty NVRAM EFI volume from an update to this bios region (your dump on the left, update bios region on the right)
