Coming back on this as a follow-up...
We were able to source Micron 7300 Pros 1.92TB NVMe's.
Here are the results, same fio command was used:

Jobs: 1 (f=1): [W(1)][100.0%][w=2230KiB/s][w=557 IOPS][eta 00m:00s] Samsung 970 EVO Plus 2TB
Jobs: 1 (f=1): [W(1)][100.0%][w=274MiB/s][w=70.0k IOPS][eta 00m:00s] Micron 7300 Pro
