Most functions are now not available in winbox if general configuration is not allowing these.
Like NV2 settings not available in 802.11 mode etc.

But what about connection rates?
Why are all connection rates in station mode still available where they bear no consequences because station gets rate set by AP?

I can remember in the 'old' days CPE could be set to lower rates than the AP was actually capable of, to increase link stability.
Haven't looked in it for some years and now it looked strange to me the options are there but it has no effect. station connects at any rate available by AP, no matter what is set in station...
