Remove border to just one ui group

Dashboard

As per subject, I need to remove the border to just one Dashboard group, but I'm stuck. Tried with CSS template, but no luck...

Does this not work (with the appropriate ID for your ui-cardpanel)?

[node-id = "514b19cf7fb14ce6"] .nr-dashboard-cardpanel  {
    border: none;
}

unfortunately, not. It is still there. I got the node-id from the browser inspection window.
<ui-card-panel node-id="4d8330e115e63aed" ng-repeat="group in main.selectedTab.items" id=...

I have fixed this way:

   .nr-dashboard-theme ui-card-panel {
    border:none;
    }

The ui-template is applied to "Widget in group".
