Answer 1

The proper elegant way to override the existing default favicon, without rewriting it is to create a ~/.jupyter/custom/custom.js file with the following content:

requirejs([
    'jquery',
    'base/js/utils',
], function($, utils
    ){

    utils.change_favicon("custom/favicon.ico")
});

Place your custom favicon.ico to the same folder.

There is a doc page that does not provide a solution, but talks about custom.js mechanism in general.
