drill the rivets out of either side - you'll be able to see there is a rivet either side just by looking at the underneath of the diffuser, then simply pop the diffuser out clip by clip - you may want to get underneath to spray some silicone onto the clips to help ease them out, really takes minutes to do.

If you do it, it will be very big help for me. I really appreciate it.

P.S. why did you replace rivet with bolt and washer

you can see where the bolts are that i've used, on the oem fitment there is one rivet and one screw so you remove these then pull the diffuser out from the clip mountings

How to you pop the corner and middle tabs out? did you have to stick your hand behind the bumper to push them out or did you wrap a regular screwdriver or spatula with tape and pry between the diffuser and bumper from the outside?

I had my car up on some ramps so was able to lay underneath the car and just used a long flat head screwdriver to pry the clips out of the retainers when I was dealing with the oem diffuser.
Wouldn't recommend trying to take the diffuser off from the outside you'll more than likely warp the bumper in places or break the retainers/clips.
