Whenever you change Rx/Tx center frequency, only the VCO is being retuned automatically.
As far as DC/IQ calibration is concerned, the calibration expects that the Rx/Tx is in final working configuration, which only the user knows when that state is ready. Otherwise if the calibration would be made to be called automatically, it’s most likely that it would report a bunch of errors (“gain too low, frequency not locked, channel not enabled…”) with most of each parameter change while the user’s initial state is being configured.
