I mean in this case the option to change it in the graphics menu when in a session could be removed, as it does not do anything anyway.
Hope they can fix it to be changeable in the session though.
I hope they can fix it because reloading the track just to change the HUD is less than convenient.
Also, it would be great that it was a setting per car, like the FOV, so we could have different HUDs selected automatically for some cars.
