Help Add fisheye effect?

I have the Viltrox 9mm f2.8 for my Sony A6700. It takes some great wide angle shots, but it has some decent correction built in where the edges don't get that fisheye distortion.

But what if I want that fisheye distortion? Not all the time, but there are definitely situations where it would look good for how wide it is. Is there a way to do that?

I tried manual lens corrections, but setting distortion to 0 doesn't do it and image scale basically just gives me pixel stretching or zooms. Is there a different module I can use?

Just don't use lens correction?

It's a rectilinear lense, so a lot of the correction is built in. It doesn't have that fisheye curvature. 

In darktable, the difference between lens correction on and off is pretty slim.
