Welcome!  :)

Nope... You want to disable the drive in bconsole.

Then, the drive will not be used for any jobs that start on the SD - this is nice when you have library with several drives 
because other jobs can continue to be started and run on the other drives while this one is disabled:
----8<----
*disable storage=mhvtl-waa_a-Autochanger drive=0                                                          │

Using Catalog "MyCatalog"                                                                                 │
3002 Device ""mhvtl-waa_a-Autochanger_Dev0" (/dev/tape/by-id/scsi-350223344ab001700-nst)" disabled.
----8<----


And a status storage=mhvtl-waa_a-Autochanger now shows the device is currently disabled:
----8<----
Device Tape: "mhvtl-waa_a-Autochanger_Dev0" (/dev/tape/by-id/scsi-350223344ab001700-nst) is not open.
Device is disabled. User command.
Drive 0 is not loaded.
----8<----


Hope this helps!
