LTC Connector DE10-Standard FPGA

I am trying to access the I2C bus on the LTC connector on the DE10 Standard FPGA board.  I have enabled the i2c controllers on the HPS. How do I now gain access to the i2c2 pins that are connected ...

According to the schematic, since the HPS_LTC_GPIO at GPIO40, I exported the GPIO40 of HPS from the Platform designer and connected it with the HPS_LTC_GPIO in my top level design.

 

Could you kindly guide me on how to switch it to low? 

What would be the address of the GPIO40 that I can access from Linux to set the GPIO40 to low?
