Employing twisted pairs only works when the signal is carried by the differential voltage on the two wires. That's not really the case for a servo PWM signal. Besides running the wires so they aren't near a source of EMI, your only real solution would be to shield the wiring.
To verify whether or not it's interference from the Ethernet cable, try unplugging the cable at the cRIO end and see whether the servo twitching when disabled goes away.
