You'd need to modify the .LD to add a QSPI section, if not already present.

You'd then __attribute__ the static/const allocation in the compiler to direct it into the QSPI section.

Something along the lines of:

/* Specify the memory areas */

MEMORY

{

...

FLASH_QSPI (rx)    : ORIGIN = 0x90000000, LENGTH = 8192K

...

}

...

 /* Constant data goes into QSPI FLASH */

 .roqspidata :

 {

  . = ALIGN(4);

  *(.roqspidata)     /* .roqspidata sections (constants, strings, etc.) */

  *(.roqspidata*)    /* .roqspidata* sections (constants, strings, etc.) */

  . = ALIGN(4);

 } >FLASH_QSPI

...

__attribute__((section(".roqspidata")))

static const unsigned char buffer[] = {

...

};

Is it designed for your board and the W25Q64, probably not
