Please define what area of flash you want to access, external or internal and is all of this under your program control? I use a FRAM module which is 32K x 8 and external.

Since it is SPI accessed you can do it one of two simple ways. Use a bigger memory chip or add additional units to the SPI bus where each memory chip has its own independent chip select from teh ESP32.
