Is it possible to set the resolution of a light's shadows via script?

I've checked all the script references, but I can't seem to find out how to change a light's shadow resolution.

I saw in a similar answer that it wasn't possible but that was well over a year ago. However, I thought I saw a system on the Asset Store that was able to adjust it. Has Unity still not added support or is there some type of work around?

To be clear I don't want to adjust it via the Quality Settings.

This is how you adjust the shadow type so I'm assuming it would be very similar.

 light.shadows = LightShadows.Hard;
 
 //Doesn't work
 light.shadows = Resolution.Low;
