Could support be added for the Garmin Fenix 8. I have imported the .fit files without any (visible) issues only the model shows up as "unknown model ID: 4536".

@mrnatrium can you please test with one of the versions available on subsurface/subsurface#4757 and confirm that this is working for you?
Also, it would be great for debugging to have a log file from a dive with a fenix dive computer, you can share it with me by email if you don't want to make it publicly available.
