Bidirectional IO connected to FPGA fabric on Cyclone V SOC Dev. Kit

I have a Cyclone V SoC Dev. kit. (DK-DEV-5CSXC6N) Which has a 5CSXFC6D6F31 Cyclone V FPGA I need to connect my own I2C slave-only controller implemented in the FPGA fabric to a couple of pins acce...

I afraid there is no bidirectional pin available in the HSMC since it is mentioned that the port has x4 transceivers, x16 TX LVDS, x16 RX LVDS as in the web page: Cyclone® V SX SoC Development Kits (intel.com).

I tried to check on HSMC interface of MAX 10 User Guide, and it mentioned that the interface has programmable bi-directional I/O pin. Refer below:

I am not quite sure if it is the same case for Cyclone V SoC Dev. Kit.

However, I can suggest you refer to this documentation for details on the HSMC specification:
