The Custimize dialog currently have no way to customize the NotebookBar.
To make NotebookBar comstomizable, the Custimize dialog should add Notebookbar tab, using similar mechanism to add/remove the button, move their position, and making them resizable.
This could be of interest. the notebookbar currently lacks some key functions by defaut
MS Office 2007 have already implemented for Ribbon UI.

I'd like to offer an customization light request.
via right click you can show/hide commands cause in the toolbar xml file there is
This option could be possible for notebookbar cause in the .ui file there you can also define
So you can define in the ui file of an notebookbar_groupedbar_compact:
Open, Save, Print, PDF (visible=false)
Right click you can change PDF from visble=false to visible=true.
I know it's not 100% the customization dialog where you can change everything, but it would be a very good start.

Configure dialogue for notebookbar
Sumit Chauhan add visibility True/False support for Notebookbar elements in the GSOC projekt 2019.
Full customization support was at the moment not available, cause you can't add commands, but maybe in the future. Initial work is already done.
Sumit maybe you can link your GSOC blog posts, ... here to get an information what and how it was done.
