You might be able to remove the module for just the SCSI card, and not the
SAS card. They likely have different drivers, even though they probably
both depend on some mpt* modules that are shared between the two cards.

Do "lspci -k". This will list the kernel modules that each pci device uses.
If they are not the same module for both the SAS and SCSI card, you can try
an "rmmod mptscsi" (or whatever driver the mpt scsi card uses). If that
works, put a "blacklist mptscsi" line into a new file in /etc/modprobe.d
(eg, blacklist-my-scsi-card.conf), and run "update-initramfs -u -k all" to
make it permanent on reboot.

If you want to undo the change in the future, just remove the file doing
the blacklist, do the update-initramfs again, and modprobe the appropriate
module.
