S32K146 FlexNVM FTFC Program sequence

For a non-sdk project, I'm implementing a FTFC driver to utilize the 64KB FlexNVM flash.

I've a question about the flash programming sequence, my current sequence is:

If 2048KB is non empty execute FTFC_ERASE_SECTOR command.

Then program the flash using the PROGRAM_PHRASE command.

And verify using the PROGRAM_CHECK command.

My question is, is the PROGRAM_CHECK command necessary and is safe to leave this command out of the programming sequence? The reference doesn't really mention it's mandatory.
