no signal on i2c_GP3_CLK

I was trying to use i2c_GP3_CLK which is on J26. I hooked a scope up and tried to get it to toggle using i2cdetect 2 and i2cdetect 3 but I got nothing on the scope. Do I need to enable these as i2c outputs somewhere?

Thank you

I2C_GP3 is reserved and not connected to anywhere. For I2C usage you can refer to I2C interface mapping table in OEM DG.
