Mathematica cannot take such integrals, even for zero-mean normal distributions. So, it is highly unlikely that they can expressed in closed form.

Here is the image of the corresponding Mathematica notebook:

An exceptional trivial case is when the two normal distributions are the same:

That is, here we get $F(y)^2/2=\Phi(y)^2/2$, by the substitution $t=\Phi(x)$.
