General discussion • Missing SMART vendor attributes

I purchased some used nvme's to use with a Pimoroni nvme base.
My PI 5's are working fine.
However, I wanted to monitor the SMART counters to see how many GB's are written and life expectancy.
On a linux system, I'd normally do
smartclt -A /dev/nvme0
And I'd be able to see the manufacturers SMART counters.

However, the above command does not report these on my Pi5?

Does anyone know why this is?
I don't seem to be able to find this info anywhere?

I know that the nvme devices themselves will report this info (before I set them up I got a baseline reading using an external nvme to SSD adapter connected to my normal desktop machine)

What I get:
root@pi5-2:/home/pi# smartctl -A /dev/nvme0
smartctl 7.3 2022-02-28 r5338 [aarch64-linux-6.6.74+rpt-rpi-2712] (local build)
