Assuming the Carta di identità states NON VALIDA PER L'ESPATRIO (which should be understood as NOT VALID FOR TRAVEL), then it was issued to a 3rd country national and is not considered a travel document (only those that are issued to Italian citizens are).
You must use your Passport.
Please add your citizenship to the question.
