Yes. You need to license the BimmerCode app (~$40) for your smartphone and buy an OBD to WiFi or Bluetooth adapter to enable wireless communication between your adapter and your phone (>$20 at Amazon). BimmerCode supports all sorts of customizations and improvements to default behaviors (e.g., silence seat belt warnings, eliminate legal disclaimer screens that must be dismissed, change the default driving mode, fold/unfold the side mirrors upon certain events).
Be aware that EV's produce a lot of electromagnetic static and that the i3's CFRP passenger module doesn't provide much electromagnetic shielding, so expect more static than usual, especially on weaker stations. Maybe because of this, an AM radio can't be enabled on 2018 or later i3's or maybe doesn't exist.
