Not sure if a DIY exists. But that diagram is a map to get it done. It shows you where the bolts are as well as the clips. So it looks like you need to lower the steering column, pull the vents, navigation screen, lower console. Then remove the bolts they show, the ones behind the passenger airbag will probably be a bear (they are on most cars). I've never done the FX, but have pulled the dash on several other cars and it's the same procedure for the most part. Once you've pulled the vents and all the climate control stuff along with the steering column dropped, it's not too bad. I'd recommend removing your front seats because you'll be on your back to get some of the bolts/clips loose and it makes it much easier to wiggle the dash cover out.
