If you want to change things on the root drive of a Mac you will need to take some steps to disable the built in security of the system. Most of these steps are the same regardless if you are on Intel or Apple Silicon. If there is a difference it is noted.
Note that all of these things put a Mac into an unsupported and less secure state.
Make sure you either perform these steps in a VM or that you reset the protections after you are done poking around
(This list is not exahustive on the details of each. Check the links at the end for more info.)
