Set viewport fullscreen and show extension UI

Hello :)

Is there a way to set the viewport full screen and also show the extension UI?
I would like to hide all menus and only show the viewport with the robot and the extension buttons on the right or left side.

I would like to do something similar to the following code, but keeping the extension UI. Is it possible?

self._settings = carb.settings.get_settings()
self._settings.set("/app/window/hideUi", True)

Thank you in advance.
