Leading Davening or Bircat Cohanim

Question: If an Ashkenazic Cohain, who lives outside of Israel, has Yahrtzeit on Yom Tov, and he davens in a community that does not permit the Shaliach Tzibur to duchen, is it better that he does not act as a Shaliach Tzibur for Mussaf and Duchens so he does not miss the opportunity of fulfilling a Torah obligation of Bircat Cohanim? I am also able to lead the Davening during other times on Yom Tov.
Answer: It is preferred to Duchen since there is no obligation to be the Shaliach Tzibur at every Davening.
