Yes. I now debugged this a bit further: Ceph uses 'sudo nvme ...' when 
executing the command, but if 'nvme' can't be found in the PATH, the 
sudoers rule does not seem to apply, because it is for '/usr/sbin/nvme'.

Seems like something with sudo changed too. Given the same sudoers file 
and not having 'nvme-cli' installed, for an unprivileged user using
     sudo nvme qemu smart-log-add --json /dev/sdc
and Ctrl+D-ing the password prompt results in a notification in PVE 7.0, 
but not in PVE 6.4.

It is in Recommends for the ceph package, but when installing via the 
API we use 'apt --no-install-recommends' for some reason. Maybe somebody 
else knows why?

I think you can use
     ceph device ls
to get the list of devices and then
     ceph device get-health-metrics <DEVICE>
