nRF52840 call DFU from own application

Hi everyone.
I am writing to have an important info, that is, is it possible to load a .hex file, preloaded in an external flash, to program from my application in the nRF52840 flash?

I need to change firmware while an application is already running.

Obviously using the BLE channel with own APP I would send a command to load a file first.hex or second.hex etc. etc.

Thank you for your kind reply.

You Update firmware via BLE or Serial?

HI thanks for the reply.
So, I don't use neither UART nor BLE, I preload an external flash and then from my application I have to take files and overwrite the nRF52840 in flash.
