I suppose anything's possible, but I would say no. A short is not a ground
fault.

I've shorted GFCI circuits in the past and the outlet has never tripped.

If it's a GFCI "outlet" it shouldn't if the short is only between hot
and neutral.

If its a GFCI "breaker" in a panel, then it of should trip on a short of
low enough impedance to cause the current to exceeed the breaker's trip
level.
