Is it possible to configure nRF5340 with dual line SPI (CONFIG_SPI_EXTENDED_MODES / SPI_LINES_DUAL)?

Is it possible to configure nRF5340 with dual line SPI using CONFIG_SPI_EXTENDED_MODES and SPI_LINES_DUAL?

I'm trying to evaluate the Analog Devices AD7616 or the TI ADS8686S – Both defaulting to this unusual setup in serial mode.

I would like to not use the QSPI currently in use for nRF7002, keeping the throughput for that device maximised.

Examples or guidance would be much appreciated!
