Stop sending verification code to EVERY device?!

We have dozens of devices within the company and all are connected to the company iCloud account. 2FA is enabled too. However every time I sign into the company iCloud account from another device or join a new device to the iCloud account, every device receives a notification informing the user that "someone is trying to access your apple account..."

This is causing an influx of support calls from people saying they've just received a message saying someone is trying to access their Apple account. Apple has kindly provided a "not received your code" link which sends a text message to a designated mobile number (much better!) but this notification crap has to stop! It's stupid that every device receives the same message. It shouldn't be like that, especially with how it's worded. There has to be a better way, otherwise 2FA will be getting disabled.

Is there anyway I can stop the verification code being sent to every device and to just use the text message option by default, or do I need to disable 2FA?
