How to remove rivet?

[eyehatetofu]

I am getting ready to chop off the lower part of my bumper and two of the four rivets holding the underside of the bumper on are metal rivets. I know the plastic ones just pull out, but I have never dealt with metal rivets. They are in there pretty tight, can I just pry them out with a screwdriver or is there anything special I need to do? I don't want to jack up my bumper more than it already is. Any help would be greatly appreciated.

Just drill it out, 1/8 inch bit or so

*edit* Nevermind upon closer inspection it is attaching part of the inside fenderwell to the bumper; its gotta be cut anyways so there is no issue. Thanks for the reply Rev. Mudd.
