There is no smartctl conf file or variable. There are no plans to add this.

Fell free to create a ticket and provide your ideas how this may work:

This only works if DEVICESCAN is used. It includes also drives behind 
MegaRAID controllers (but no other RAID controllers). For individual 
entries, -d megaraid,N is still required.

"smartctl --scan" uses the same functionality as the DEVICESCAN in 
smartd.conf.
