How can i Control LED in nRF9160 SIP Without using any Microcontroller ?

Hi 

              We are designing a custom board using only nRF9160 as a tracking device.
               I am connecting Switch and LED to generate various events.
               Is is possible for me to program nRF9160 module without using any controller in the device. (Programming to control LED)
               We will be sending a data through LTE whenever any defined events are notified by Switches and LED.
