Prevent ACM-created units to be deleted?

[roguetrooper 2]

Is there a way to prevent units and vehicles that have been created by an ACM (Ambient Combat Manager Module) to be automatically deleted again?

Especially those that are out of sight/range of the player/s.

Maybe this:

[bIS_ACM1, 400, 700] call BIS_ACM_setSpawnDistanceFunc;  // This is the radius on where the units will spawn around the unit the module is sync'd to, 400m being the minimal distance and 700m being the maximum. Minimum is 1 I believe.

I've been using this command, but it only influences in what radius the units spawn. By my own experience it does not prevent units from sudden un-pop.
