I used two SPI interfaces in this add External Grove FLASH Chip Demo

@PJ_Glasso

SPIClass SPI_2(NRF_SPIM0, PIN_QSPI_IO1, PIN_QSPI_SCK, PIN_QSPI_IO0);  // Onboard QSPI Flash chip
Adafruit_FlashTransport_SPI QflashTransport(PIN_QSPI_CS, SPI_2);      // CS for QSPI Flash
Adafruit_SPIFlash Qflash(&QflashTransport);

SPIClass SPI_1(NRF_SPIM3, D9, D8, D10);                       // MISO, SCK, MOSI /EXPANSION FLASH// CS pin D1 (hardwired)
Adafruit_FlashTransport_SPI EflashTransport(SS_SPI0, SPI_1);  // Flash Type
Adafruit_SPIFlash Eflash(&EflashTransport);

this snip from that code that may be relevant for using 2nd SPI int on the Nrf52840
