AD9364 How to control Clockout.

Hello!

We want to use the fmcomms part of the board to give the clock to an external source to sync with the AD9364. From the GUI there is an easy way to do it through the AD936X tab -> Clockout -> XTALN DCXO Buffered. The problem is that when you restart the board it will be set to its default value of "Disable". How do you change the default value or change it through the IIO commands (if there is any bindings to that register)?
