You can do so using if.
See following example:
--------------------------------------------------------------
config ONLY_HAVE_ONE
	prompt "only have one?"
	boolean

if ONLY_HAVE_ONE
config FOO
	bool foo
	default y
endif

if !ONLY_HAVE_ONE
choice
	prompt "multiple values"
	default VAL_FIRST

config VAL_FIRST
	bool "First value"

config VAL_SECOND
	bool "Second value"
endchoice

endif
--------------------------------------------------------------

You should be able to modify this for the usage you ask for.

Hope this is useful,
