You can't side with the Enclave because F3 has a linear main storyline. You CAN aid the Enclave in the end, though. Simply deploy the virus without Broken Steel loaded. You die, BS never happens, and the Enclave simple waits until everyone (including the BoS) has been poisoned, then takes over the wasteland.
In the end, you can aid several factions (Outcasts, Treehuggers, Slavers, Tenpennyites, Lamplighters, Megatonners, others), but for the main quest, you have to work alongside the Brotherhood. If you don't like it, just don't do the main quest: roam the wasteland with your follower of choice while your dad wanders around Tranquility Lane sniffing fire hydrants.
