No, in our current best-supported model of the universe (Lambda-CDM) the concept of “before” the Big Bang is meaningless. It is the apex of the spacetime “bell” from which everything emerged.
But something must have triggered the big bang. The model might not support this, but this only means the model is insufficient to describe what goes beyond our known universe.
That’s a philosophical question, not a scientific one, since it’s by definition beyond the ability of science to answer. It suffers from the infinite regress problem which many people invoke God to solve (the uncaused cause) but that’s not very satisfying, is it?

Obviously God did it. /s
