Yes, displayed but not edited.

Hm, it's disappointing that EXPERT is not mentioned there somewhere,
when using menuconfig or nconfig.
When using xconfig, and selecting "Virtual terminal" VT, xconfig help does say:

type: bool
unknown property: symbol
dep: TTY && !UML
prompt: Virtual terminal
dep: TTY && !UML && EXPERT <<<<< so the prompt depends on EXPERT
select: INPUT
dep: TTY && !UML
default: y
dep: TTY && !UML
