UART DFU from nRF9160 to nRF52840

I am looking to DFU an nrf52840 over UART from an nRF9160. The board is set up similar to the Thingy:91. The firmware will be downloaded over LTE on the 9160 and will need to be sent over to the 52840 via UART. Would be best place to start be the smp_svr sample? I know the sample instructions suggest using the mcumgr Command-Line Tool but I need to do this from the 9160. Does the smp_svr provide support for the 9160 to run the DFU commands and start an update on the 52840?
