Shifter Knob Removal Situation

Ready to remove the console. Removed knob set screw. Button and knob are interlocked. Turn to loosen and will not break free. Pull up and turn, push down and turn, same result. Feels like the button has bonded to the cable stud. Pretty sure last time it was out was when the carpet was replaced over 20 years ago. Wonder if someone used Loctite? When turning it's like winding up a high tension rubber band and I'm afraid if I force it the cable will break somewhere.

Thinking best course is to break apart the button so I can remove the knob. What is the best way to do that without damaging the knob? Drill?
