Edge explore 2 sync all Garmin 955 activities

I just received the edge explore 2.

On setup it’s started syncing all my previous activities from my Garmin connect account, including running, Pilates, etc etc.

i want it to sync up to Garmin connext, not litter my device with all my previous activities. I can find a delete all option or an option to stop it syncing all these activities.

please help!
