Is there an easy removal trick for the Mopar large headed plastic “rivets” on under body splash shields and inner wheel well liners?

In the past I have always just snipped them off with electrical side cutter pliers, and then bought new ones,
but I thought:
“maybe there is a slick trick to remove them and then re-use them.”

I just tried wrapping thin but strong fishing line around the head and pulling down, but no luck.
