Hide "disconnected" icon for jupyter-widget

[wang-yinan]

Is there any way of hiding the "disconnected" icon for widgets when there is no python kernel?

I have a couple of interactive displays that are showing the icon like so:

The first is an ipyleaflet map that doesn't expect any user input (apart from panning, zooming etc) and the second is a progress bar generated by tqdm.notebook.

I see that the icon itself is just some css styling, is there an option to just disable it?
