Unauthenticated access to the Web interface, to see graphs?

Both “real-time” graphs under Foris and collected graphs under LuCI are great but I would like my users to be able to see them. Both Foris and LuCI require an authentication, even for read-only activity. Is there a way to have unauthenticated access to some display functions of the Turris Omnia?

(In the mean time, I directed the users to the LEDs, thanks to the excellent trick in https://discourse.labs.nic.cz/t/led-color-based-on-bandwidth-usage/1262 )
