BBB, BB-View and I2C

I am using a beagle bone with angstrom os and bb-view 4.3 inch LCD and am wanting to use i2c as well.

I see that the bb-view uses pins P9-17/18 which are i2c1 but that is also uses P-20 as GPIO for LED1 which seems rather silly to blow a I2C port for simple digital output.

Question is can I still somehow use I2C 2 (Pins P9_19/20) as I2C? Can I somehow disable LCD’s use of this pin?
