The Scsi_Cmnd::scsi_level member looks promising for
controlling whether that is done:
if (SDpnt->scsi_level <= SCSI_2)
scsi_cmd[1] = (lun << 5) & 0xe0;
We just need to be careful with its values (from scsi.h):
#define SCSI_UNKNOWN 0
#define SCSI_1 1
#define SCSI_1_CCS 2
#define SCSI_2 3
#define SCSI_3 4
