How to bypass parental controls forgotten passcode?

I put parental restrictions on my child's iPhone 6 iOS 10.3.3, however, I forgot the passcode I put them under. This would be an easy fix if I had not made it so difficult for myself by requiring the passcode be used to manage all location tracking, and before restarting the phone. According to wikihow.com, I should need to do either of these things. I'm not looking to install any hardware/software/anything really, is there any way I can bypass the restrictions this way? I don't mind loosing the information or data on the phone, there isn't much.

You can't bypass the controls.
You will need to restore your iPhone (probably in DFU mode) with iTunes on your computer.

Ha! Done the same. Nope, there's no way unless you can remember it. If there was a way, there would be no reason for a password in the first place.
