Not that I know of, the programming for such a plugin is quite intense so I don't think any music software developer would give away such a plugin. If there is a free de-clicking plugin I bet you it doesn't work that well.

You can manually go in and get rid of pops and clicks though, my step dad does this to recordings of old vinyls with Audacity which is free.

I use the oxford de-clicker, but it isn't free
