make grenade launcher projectile not explode

How can I make the gl projectile never explode?

Maybe set the original range, where the grenade not explodes, to 9999, or sth like that.
is there a dvar for this?
(it should only explode, if it directly hits the enemy)
is that possible?

so you essentially want to completely reverse its current objective. to explode wherever else except within set range, then explode upon impact.

I've always wanted this too, but I think its hardcoded into the game.
Not quite sure though
