Note that the second USB-C port shield may fling off of the frame when you detach it. You can place a finger on the shield to prevent it from flinging.

Repeat the previous step for the other corner of the shield closest to the left speaker recess.

Continue prying up the edge of the shield closest to the left speaker recess until the shield detaches from the frame.

Remove the shield from the frame.

If the shield isn't completely detached from the frame, pry up additional areas on the edges of the shield.
