Can't find expert mode in dudu OS v3.6

Hi, I recently got a dudu4 unit, it us currently on dudu3.6, but i can't seem to find the "expert mode" setting.
I tried all menu's, but i can't find the other section anymore, it just says labs, but no expert mode.

Can someone help me out?

Settings i would like to change and can't find either:

Rear camera view disabling, since i don't have any.
Car speed controlled volume
(i saw forum posts for both of these, but i can't find them at all)

Thank you!

Small update, i found both settings, not sure if related, but i think they appeared after entering the factory settings once under the vehicle menu.
The reverse camera setting is now in factory settings -> advanced
