The last type of nonvolatile information in flash is chip-level protection. This consists of one byte that restricts access to the chip’s resources (register, SRAM, and flash) by an external programmer or debugger.

Nonvolatile memory programming refers to the programming of flash memory in the PSoC® 4 device. This chapter explains the different functions that are part of device programming, such as erase, write, program, and checksum calculation.Cypress-supplied programmers and other third-party programmers can use these functions to program the PSoC 4 device with the data in an application hex file.
Please check this discussion , it discusses the limitation of Jlink to program hex file generated by PSoC Creator:
J-Flash should only be used with data files that solely contain (programmable) flash addresses.
This limitation comes because Jlink can't program Nonvolatile memory in the PSoC® 4 device
Please check page#211 of this document, as all system calls are part of Nonvolatile memory

So, it seems from all this above info that JLINK can't change the chip protection setting
