If you cut that section out you could be affecting the structural integrity of the roof. There is a reason why the ribs are welded there.
What I did on my roof raise was to remove the three rivets at the hat channel, slightly pried open the space between the drip rail and inside sheet metal then I slid the sheet metal up under the drip edge.
Then to hold it up I used a self tapping screw in the rivet hole where I removed the 3 rivets.
two screws, one at each rib should be enough to hold the sheet metal up in place while you work on installing/securing the rest of the panel.
If you can zoom in on the pic I uploaded you can see the sheet metal screws. They were replaced with rivets when I got to that particular rib.
