The answer is no. To do so would be contrary to God's nature. You ascribe a human trait to him when you consider that for God to move one mountain that is larger than another he must exert more effort. God does not exert effort. He just moves it.
The implication of the question is that God's "inability" to limit himself is proof that God is not omnipotent. But this is simply a logical "limitation." God truly is all powerful. The "inability" to limit Himself is, in fact, an aspect of his omnipotence. Self-limitation would represent a defect.
