Hi. If I need to disable default component in IDF (\esp\esp-idf\components\hal\i2c_hal.c) and replace with my own components. Is it possiable to disable the hal at cmake and replace it with my own?

One quick and easy way is to copy any components you want to modify from the IDF into your project's components directory. While building, project-local components will be given preference over external components of the same name.

yes, you are correct. Just copy whole compoent to the project file will be ok.
