You can lock the flash memory as much as you like. The PRAM on the Phison chip is unaffected.
What is being reprogrammed is the Phison control chip. There is no write enable pin on the Phison chip. It has a pin to control the write lock of the flash memory, but that has no effect on the Phison PRAM where the firmware resides.
