Sync collection from explore.garmin.com to Garmin Tread Overland

I am thinking of purchasing  a Garmin Tread Overland,

I just want to sync my collection that I have done in the explore.garmin.com website to the above.

I do no want to use the Tread app on my phone as I will only be sync waypoints in my collection.

I think I need to download the explore app on the Garmin Tread unit itself

Is this possible tks

ps I know this is possibly with the Garmin Overlander, but I want the Tread so that I can download Birdseye view
