No.

> I mean, the Constitution explicitly grants the Court those powers.

The Constitution defines the judicial power of the United States to include deciding certain classes of legal controversies, including those arising under the Constitution, and provides that the Supreme Court is the organ which executes that role in both an explicitly defined set of cases, and in certain other cases as Congress directs. But that is pretty far from explicitly granting the Supreme Court the sole and exclusive power to interpret the Constitution.

Interpreting the Constitution is no less essential to the Supreme Court's role of deciding certain legal controversies than it is to, e.g., the President's role of seeing that the laws -- including the Constitution -- are faithfully executed, or the Congress's role in carrying out the powers and responsibilities it has defined in the Constitution, or the public's role in evaluating the performance of all three branches and electing members to the two political branches.

The Supreme Court (or the judiciary, or even "government officials" more generally) isn't a special priestly caste to whom the contemplation of certain mysteries is restricted. That would be contrary to the entire concept of government of, by, and for the people.
