How should user find default values of parameters?

E.g. for disableHTTPRoute and sessionAffinity. I couldn't find it in api doc [1].
Looking into CRD [2] I can't see defaults neither. So can user assume default is false?

Could it be somewhere declared explicitly? I think best would be CRD or at leas api doc.
