How to change i2c peripherals clock


I am working on a project at university and the LiDAR sensor we are testing requires a lot of bandwidth on the i2c bus. After some research i still haven’t found the peripherals clock config file to change the parameters and use the i2c in fast mode, any clue about the file path? I am using Armbian 22.11.0 on the bpi m2 zero.

Thank you, M.
