Internally, this bridge is an ChipOne ICN6211 which loads its register configuration from a dedicated storage and its I2C does not seem to be accessible. The ICN6211 supports up to 4 DSI lanes, so this is a hard limit for this bridge. The lane configuration is preconfigured in the bridge for each of the WaveShare panels.
