My use-case is to have multiple sensors with the same I2C address attached to the PI and also a LED screen that I want to attach on it's own. I found that there is a software level overlay BUT it is super slow and I am looking to see if there is a way to activate any of the PI pins as I2C pins on the hardware layer.
