Copying and remotely deploying a build across multiple devices
Using root and tasker rules you could pull your settings.db from a central point of your choice, but that would erase any settings.

A more elegant way would be a tasker rule that sets all the settings in the database.

For Wi-Fi AP you would have to pull the wpa_supplicant file from somewhere using the same method or use Linux tools to alter the config file.

Other settings would require finding associated config file or database and use above methods.
