Physics is concerned with causality in the framework of natural law. Causality there is deeply embedded in both the two main fundamental theories: QM & GR. In QM, because time is open and things happen whilst in GR, its proveable that the very structure of spacetime is causal. This is a theorem of Malament who showed that a spacetime could be rebuilt (upto a conformal factor) from a knowledge of its causal structure. This has prompted the development of the causal set programme in Quantum Gravity.
More broadly speaking, as al-Ghazali pointed out, physics is merely correlational, requiring the intervention of the Absolutely Real to make what is wholly unreal, real. But this is outside what is now understood to be physics - if not what was understood traditionally as metaphysics. Of course some physicalists take physics to be the ground but this is not primarily because they are physicists or even interested in physics but because they are a certain tribe of materialists.
