You either switch the controller to "HBA" mode using its setup utility, or keep it in current "RAID" mode but configure your SSD as "Non-RAID" drive. Also, you must use mrsas(4) driver instead of default mfi(4) to get TRIM support for SSD. mfi(4) has no TRIM support at all. You may switch to mrsas(4) after intallation, though.
