i2c2 pins in cheetah v2.0 #6

There is a discrepancy in schematic (Cheetah_Board V2.0_SCH.pdf) of the board and pin definitions, i2c2 should be PB10/PB11, but in schematic it's PB10/PB3? There is also a note about capacitor on PB11 that disables i2c, so what is the state of the hardware? I'm trying to connect ssd1306 display via i2c to be used in klipper, but it timeouts on PB10/PB11.

@GerogeFu Any ideas? I am also not having luck with any i2c devices on EXP4. Looking at Klipper's i2c defs, there is no PB10/PB3
