Question [Q] Mobile data 2G/3G toggle in tasker

I wanted to set a profile and change mobile data from 2G to 3G. But this option is not available for Stock ROM (I've used this option on custom ROMs, and it work smooth as ever).

Does anyone know what I need to do, to make it work??

Any tutorial for modding the apk is also appreciated.

I am running rooted unlocked stock 4.4.4 xt1052 (Indian).
