[Plugin: WordPress Mobile Pack] Disable posting comments from Mobile devices

I installed WordPress Mobile Pack and its working great. I am using livefyre for commeting system and I found that the livefyre is not optimizing when site runs on mobile devices. is there any way to disable commenting from mobile devices but allow comments from desktop users?
