Restricting/Hiding Social Logins to Desktop & Web?

Until I can come up with a better solution or at least a better understanding of why social logins are fairly broken in my mobile app, I would like to keep the social logins active and available but hide them from native mobile users while keeping it accessible to desktop web and mobile web users.    

I looked for blocks and pages as you normally would but I didn't find what I was looking for. Is this currently possible?
