Before you bend anything, it looks like that bar rests in an open-ended bracket, so you should be able to move the bar to see the effect it without bending anything. I think it would be good to do this test because I'm not entirely sure this is your problem. You may be able to use some zip wire ties to pull it back a bit and hold it there while you test the new position.
Once you see the results of this test, you can choose to proceed further to straighten the bar.
It's always good to do small tests that can be undone before making any permanent changes.
