OTG Drivers To non-otg Android Phone.? My Phone Details : 

Android 5.1 Lollipop

Model No - LS-4005

Model- LYF FLAME 6

My phone doesn't support otg drive.
Can I install otg support manually ?
If yes, please tell me how.
The kernel has to support it, so a custom kernel would have to have the necessary modification/modules to allow OTG (meaning that you would have to download the source, modify it, compile it, flash it to device).  Otherwise the manufacturer would have to implement it.
