Is it possible to remove language filter and still use esmobile template?

When I checked my Pagespeed insight on google it always shows that i had redirect url from http://btsudama.com to http://btsudama.com/en

Generally in joomla we can eliminate this redirect by disabling language filter plugin. But if i disable this plugin esmobile template will not be rendering on mobile.

Is there any other alternative for it? so that i can still render esmobile template and eliminate redirection issue?

Thank You
