No, you don't. Erasure is always automatic.

Erase commands only offer the possibility of performance
optimization. E.g., rather than letting the on-board
controller decide what to erase and when, it may pay to
erase smaller or larger areas in one go, or to increase
the perceived or real-time write performance by erasing
ahead of time.
