Another HELP removing a border thread

I recently updated HACS and one of my custom cards are showing a border that never showed in the past.

Here’s a screenshot:

I want to remove the border around the date, time and temperature above. The same for the border around Alarm, Automation, Mailbox and Hub.

I was successful in removing it from around each item on the chips card (there used to be another border around each item - Date, time etc) but can’t apply the same code to the other.

Here’s my code:
