2001 BMW 330xi Question: can I disengage the 4wd to get better mileage?

in a word, no.

No. The x-drive is a complex system with an intelligent traction control. No disengagement is possible without turning most of the warning lights on and getting systems going into limp home mode.
If you want the best possible gas mileage make sure the engine is 'tuned up', filters are clean and tire pressures are correct.
The manufacturer also recommends to replace the O2 sensors at 100K miles.
