You can't. Period. End of story. And thank ghod for that.

Yes, if you use the scary rooted device facilities to have some code run as root, you can in theory do whatever you want. In practice, it may be quite hard to get around this restriction, and the platform is often designed to be that way. You will at the very least need to mess around with the state maintained and/or stored by the package manager, and will likely need to cause the user to reboot the device to get changes you make as root to actually have an impact. And of course you are then messing with deeply internal implementation details of the platform, which means breaking all over the place across different versions of the platform and different builds from different manufacturers.
