First of all, "wanna" is never written in acceptable English. Always write out "want to" no matter how it is pronounced.
Your sentence: "I don't 'wanna' know more who you are" is awkward. It would sound better to say it: "I don't want to know who you are anymore." You should NOT change "anymore" to "more".
The sentence, as written, is equivalent to the alternate meanings you suggested.
