No. The flex plate is on the transmission input shaft between engine and transmission. To get it out you have to pull the transmission. Fortunately, it's not hard to do.
In some cars, you can get the rear bearing by dropping the transmission. For the rest, no.
You will have to slide / move the transmission back enough to get your hand up in between the flywheel and toqure converter so you can remove the flywheel bolts. You do not have to compleatly remove the transmission. I do it all the time.
You could remove the transmission and pour it out of the rear driveshaft seal. But I would recommend dropping the pan.
