RE: NRF58122 using SPI with softdevice cannot sleep

Yes, the SPI requires the high frequency clock and therefore will burn power even when not in use but enabled. I am using the nrf_drv_spi_uninit function in my SPI driver. But you could probably call nrf_spi_disable yourself, or even access the peripheral register directly using

p_spi->ENABLE = (SPI_ENABLE_ENABLE_Disabled << SPI_ENABLE_ENABLE_Pos);
