So no BLE in the bootloader at all, then? 
 In that case, you need to remove the ret_val = nrf_dfu_set_adv_name_init(); in ble_dfu_buttonless_async_svci_init() in ble_dfu_unbonded.c. 
 But really, it doesn't make much sense to use a buttonless dfu service if you are only using a bootloader that only supports UART. If you intend to have a bootloader that supports both uart and BLE, then you can put the nrf_dfu_set_adv_name_init() when you have included the BLE transport in the bootloader.
