STM34f429i Discovery i2s/i2c question

Hello everyone.

I am building a simple car audio/video player, and the 429i with the LCD built into it seems perfect. I want to use a different DAC, specifically Ti's PCM5122, so that I can use higher grade amps, among other things. I've nutted out the DAC config (not as simple as it sounds, it's quite a powerful part), but when I fire up CubeMX and tell it I'm using a 429 disco kit it won't give me access to any of the I2S busses onboard. 
I havn't got the 429 kit yet, it's in the mail, but I would like to know if I can access an i2s and i2c bus while still using the LCD. I can't find anything in the documentation about this, and a search here bought up nothing.
Has anyone else had this issue? or is CubeMX just messing with me? 
Thank you :)
