R7, missing websocket?

hello

I have a DS-2DE3304W-DE and a DS-2DE4A404IW-DE with latest firmware.

based on release note 5.6.0, websockets should be present in the network configuration directly from the camera (from web browser)

I do not see these. Reference; pdf release note 5.6.0 point 3.2.4, screenshot. First 2 options

is there a way to get these? Do i have to do a restore / reset of the camera?

thanks
