Unable to remove devices from Apple Account due to Stolen Device Protection

Can't remove devices from account on the web

Because Stolen Device Protection is enabled, some of your account information can't be changed on the web. To remove a device from your account, use your Apple devices where you're signed in with your account in the Settings app.

And my iPhone is in DFU mode so I can't turn it off either. How do I fix this? =/
