iphone is disabled connect to itunes

For context, this is an iPhone 6 that hasn't been used in years. I want to get rid of it but want to delete my data first before I do, however, this screen pops up immediately upon powering up and has stayed this way for a few weeks so I cannot log in to delete my data. I have never even tried a passcode (so haven't had multiple wrong attempts) - this screen won't even let me enter in a passcode.
