It won't hurt at all to wait, Barefoot. Pruning knockouts is more for esthetics and to keep the plants in bounds.
Knockouts are Rugosa roses. Hardier than a fancy hybrid, but often unpredictable and ganglier as they grow.
Take a look for branches that are crossed or rubbing and prune those. Prune anything broken or dead and you can leave the rest and enjoy your flowers.
It is just EASIER to prune if the plants aren't in full leaf or flower, as you can see clearly to prune.
P.S. GOOD tip from PaPaLarry! I keep my alcohol in a spray bottle and spritz the clippers between plants.
