Hi, 

You can have a look at the bootloader documentation and have a look at my tutorial here.

I got confused where I should execute this code.

Can u help me where I should execute this. For example in which directory I should execute

nrfutil pkg generate --hw-version 52 --application-version 1 --application nrf52832_xxaa.hex --sd-req 0x98 --key-file private.key app_dfu_package.zip

This code is to generate the .zip file which is the file that you can use in the DFU master (phone for example) to send the image to the device. Have you followed my tutorial ?

Is it possible to Update the application without writing the bootloader?
