smartmontools and kern.securelevel

I run smartmontools on my storage servers, to launch periodic disk tests  
and alert on disk errors.

Unfortunately, if we set sysctl kern.securelevel >=2, smartmontools does  
not work anymore.
Certainly because it needs to write directly to raw devices.
(details of the levels, -1 to 3, in security(7))

Any workaround to this ?

Perhaps we could think about allowing SMART commands to be written to disks  
when sysctl kern.securelevel >=2 ?
(I assume smartmontools writes SMART commands)

Thank you very much !
