Headlight adjustment bracket attached?

So my passenger side headlight can be pushed in on the left (when looking straight on). At first I thought the frame was bent but upon further investigation it looks like the dial housing which is used to adjust the headlight is broken. Is this an easy replacement or do I have to take out the black metal frame which holds the headlights, and if this is the case I’ll need to remove the bumper as well correct?
