        help
            If this option is enabled, NVS will be initialized and calibration data will be loaded from there.
            PHY calibration will be skipped on deep sleep wakeup. If calibration data is not found, full calibration
            will be performed and stored in NVS. Normally, only partial calibration will be performed.
            If this option is disabled, full calibration will be performed.

            If it's easy that your board calibrate bad data, choose 'n'.
            Two cases for example, you should choose 'n':
            1.If your board is easy to be booted up with antenna disconnected.
            2.Because of your board design, each time when you do calibration, the result are too unstable.
            If unsure, choose 'y'.

            When using a custom partition table, make sure that PHY data
            partition is included (type: 'data', subtype: 'phy').
            With default partition tables, this is done automatically.
            If PHY init data is stored in a partition, it has to be flashed there,
            otherwise runtime error will occur.

            If this option is not enabled, PHY init data will be embedded
            into the application binary.

            On some ESP targets, the USB PHY can interfere with WiFi thus lowering WiFi performance. As a result, on
            those affected ESP targets, the ESP PHY library's initialization will automatically disable the USB PHY to
            get best WiFi performance. This option controls whether or not the ESP PHY library will keep the USB PHY
            enabled on initialization.

            Note: This option can be disabled to increase WiFi performance. However, disabling this option will also
            mean that the USB PHY cannot be used while WiFi is enabled.

            method is used by default for RF calibration. Full calibration takes about 100ms
            more than partial calibration. If boot duration is not critical, it is suggested
            to use the full calibration method. No calibration method is only used when the
