When I first read this post earlier I was going to say that just tight enough was the best amount but in hind sight that means you need to have had slippage at least once. I don't know if I'd want the chance to gauge up a carbon drop out experimenting.
Does the OP have contact with the manufacturer or does the seller have info? The Op is wise to worry. Andy.
I agree that the OP has reason to worry, or at least may have.
But he has no choice about getting wheels tight enough not to slip. So a reasonable coarse of action is to use track nuts and axle faces with good bite, so h gets the most hold for any compression, then err low on the torque, and go tighter if the wheels slip. I wouldn'y worry about the front wheel, it doesn't need an awful lot to stay put. It's the rear that may or may not be a problem.
