How to disable Seadragon navigation before openDzi()?

Question

I use only custom navigation controls in my Seadragon project so I disable all the default controls with clearDefaults() method. However, I can do it only after processing a DZI file which causes my server to look for navigation buttons and generate many GET errors.

Could I disable it even before calling openDzi so that it doesn't even look for these images at all?
