RBR850 cannot disable SSID

I just bought the AX6000 RBR850 yesterday to upgrade from My RBR50 and to my surprise i cannot disable the SSID broadcast the way i could before. Can this setting be brought back. I dont need all the neighbourhood to be aware of my presence and try to connect all the time. I think it is a basic security measure, so why has it been removed?

It would also be a good thing to be able to have different SSID per band. So that we can set specific device on certain band. on both main and guest channel.
love the product but for an upgrade from my older set, i am a bit disappointed there is not even an ON/Off button anymore.  Please put those setting back up.

Thank you for your attention on the subject.

cheers
