The 2G toggle can also be found in some other phones, but not every phone manufacturer has support for configuring their modems like that or has bothered to keep the setting in their settings app overhaul.
I know that setting, but I'm not entirely sure if that controls a preference or a mandatory cell config, and if it will prevent downgrades from the network side or not.
Some manufacturers and most custom ROMs also seem to offer that option without a dial code, but I haven't found any documentation about that feature yet to be sure it actually forces the modem configuration. I've found mentions online about this setting being changed without user interaction, so there seems to be a mechanism on some phones (carrier-branded ones maybe?) that alters this config.
every modem have to have that control. and you can access it on every model I've ever seen with the code i shared. i think it might be a requirement for some of the regulations they plaster stickers for.
having the ui it not is a balance between playing nice with over reaching law enforcement and enterprise clients.
