You can quite easily change your regulatory domain on Linux, as well as change stored settings (through wireless-regdb) in it. CRDA is run in user-space.<p>For example, `iw reg set` to BO ro JP will remove many power and channel limitations.<p>Yes, it&#x27;s possible to have these settings stored in a tertiary firmware, but it&#x27;s not common anymore. The hardware is the same, the driver and stack simply limit it based on what the OS requests.
