TV Mode for Dashboard, get shareable public link

We would like to display our dashboard on a screen in our office, it would be great if we can get a shareable link where no login is needed (just like on the boards where you can click share settings)

unfortunately the dashboards have no way of being shared publically, and TV Mode requires you to click a button.

I know this feature has been requested many times, if it will not be added in the forseeable future I would already love to be able to just call https::// so that it would automatically start in fullscreen then we can at least make it work with a logged in user on the screen.
