how do i get data off a disabled iphone 7 that hasnt been backed up

As is always the case, backups need to be made and kept up to date before something happens. After something serious happens, your options are zero and your data will be lost.

Data recovery will not be an option on any iOS device with Secure Enclave, since the data is encrypted and there’s no way to decrypt it even if pulled from the device.

Sorry. Once the phone is disabled, there is no access to the data. It cannot be removed, backed up, recovered, or anything like that. You have to restore the device to remove the disabled status, and all of your content will be lost.

You will be able to restore to your last backup, and if you have none, then you will have to set the device up as new. Illustrates the need for regular backups. iCloud backups can be done automatically daily at night when you are asleep, or you connect the device to the computer and iTunes on a regular basis.
