It is possible, mkfs with "-O ^has_journal" but then of course you ...
have no journaling.
However, Intel has always said, I think, that you should treat their
SSDs just like you would treat any other hard drive, so I probably would
not hesitate to leave the journal intact.
There is a write lifetime of course, but I think it's much better than
if you were writing to, say, a securedigital card.
