Unprotect EPCQ using Quartus programmer command line interface

I'd like to unprotect an EPCQ flash memory device programmatically, preferably using the quartus_pgm CLI. I know that the Quartus programmer GUI has an option to unprotect the device before programming (see attached image) but I could not find a corresponding CLI option. Is there a way to do it?

    Either it does not mention locking of external flash device or I am overlooking something. Did you have something specific in mind?

    Hi ddroe,


    I have talked to the internal expert and he said that this setting can only be set in GUI, after you save the setting, it will save to the quartus2.ini in user directory, and this setting will apply to quartus_pgm subsequently.
