You can use kodi's media manager and just copy a file (1 GB) to the internal memory of FireTV.
Don't forget to delete it and check how much bandwidth you get. 4K HDR might be too slow via 100 Mbit/s LAN adapter (< 48 Mbit/s real throughput) and might only work via 5 Ghz Wireless.
I don't use LAN adapter, i use wireless network at 5 Ghz (same network both for the shield and for the Fire Stick).
