Please read Apple’s white paper on the security chip:

They provide a setting that lets you disable the boot security at will, allowing you to install Linux or any other alternative OS. Security features on macOS (as opposed to iOS) are generally optional, but enabled by default (as is the sensible choice).

They don’t provide you the ability to reprogram the T2 itself, which is a shame but not entirely without merit - compromising the T2 chip would be far more dangerous than compromising the OS in terms of persistence.
