            The LDO channel 1 can be used to power the SPI Flash chip,
            because the channel 1 is enabled by default after power on reset.
            If your SPI flash chip is not powered by ESP internal LDO, you can disable this option.
            Then you will free up one LDO channel for other general purpose.
