AFAIK, with Duokan you loose all connectivity to Amazon. So, yes, Amazon should not be able to install anything while Duokan is running.
But if you run the original firmware (Duokan does not override the original), then they should be able to upgrade it (not sure if this will harm the Duokan installlation though).
