No. There is only set and unset. WITH_option="NO" has the same effect as
WITH_option="YES".

I think this is confusing and often leads to unintended
consequences, but I and also say that some of the WITH_options documented
for src.conf (the man page is auto-generated from the code) are either
non-functional or broken. I've had some interesting issues with unexpected
interactions of WITH_options, as well. Be very careful!
