BigGreenThumb and thumper60 are spot on, there's no rigging anything.
You have 3 options...
1: Vent your exhaust back into the house and deal with the extra humidity and have no concerns of backdrafting from the furnace.
2: Crack a window somewhere else in the house, hopefully allowing the air to be somewhat conditioned before hitting the grow room, and having no worries about backdraft
3: Get a high efficiency furnace, they have their own ducting for outside/combustion air, meaning it won't be starving for air when running the exhaust outside the house.
For the record, just running the hood vent above my stove and a bathroom exhaust fan at the same time creates backdrafting/CO issues if the furnace is running.
Best wishes and be safe.
