First, it seems like you are trying to flash data, that has overlapping regions. Which means, your hex file(s) describe the content of single flash byte at least two times.

Second, to be able to use nrf connect to flash new firmware onto the dongle, without a SWD adapter, there have to be a suitable bootloader on it. You can either use tag connect cable to connect your dongle to a SWD adapter (your first picture) or you have to lookup the documentation for your dongle, if there is already a bootloader and how to use it.
