This feature is available in the pro version only.

Free version

In the free version, you can hide the slider with custom coding using Media Queries:

E.g.:

@media only screen and (max-width: 440px) {
      div#n2-ss-4 {
          display: none;
      }
}

where the 4 in n2-ss-4 is your slider id. You can put this code to your theme's CSS file.
