Even though my character noticed it was trapped there was no option to disarm it.
I haven't played the update, but if you are talking about the trapped chest in the hidden area to the 'left' of the druid's grove entrance, in the older versions there is a key that will open the chest without it going off.
Jump to the island in the middle of the waterway. Go around to the bottom, which is hidden if you are looking at it from the path. You will find a body with the key. The chest can be opened with the key without traps going off.
Good to know I'll keep this in mind for another run. I do still think the new traps shouldn't be a thing.In fight I was going over to the body to use speak with dead, but I had to reload, because the traps saw me, and tore my entire party to shreds before I could react.
