TA parking/ driving lights
There is no easy way to modify this operation without side effects. The function is controlled by the DRL module. It has various relays and circuits that turn the filaments on or off for DRLs, parking lights and turn signals. Basically, what you would want to do is trick it into thinking the headlights aren't on even when they are.
You can try disconnecting the yellow wire at the DRL module so that it doesn't get power when the headlight switch is on. This will have the side effect of disabling the automatic headlight feature (on Camaros and Canadian Firebirds) and may have other side effects as well (so try it at your own risk and test everything before you drive anywhere).
