seeeduino 328 GLCD KS0108 & I2C

Good morning,
can i use ADC6 or ADC7 to release analog 4 used to Enable the GLCD?
I need to use A4 and A5 for I2C comunication.
Otherwise use ADC6 or ADC7 instead of analog 0(CSEL1), 1(CSEL2), 2(R/W) or 3(D_I)?
Is there another solution to connect LCD display and I2C at the same time in seeeduino 328?
Best regards

ADC6 and ADC7 could only be used as Analog input.
