Is it not just time to have one of those parent/almost adult son conversations and come to a reasoned conclusion?
I wouldn't bother with trying to get MAC address filtering working - they will just workaround it by cloning another device's MAC address which is allowed access (e.g. a smart TV or Alexa or smart plug etc.) - or they can just set a static IP address on the device bypassing the DHCP controls.

They would have to know what those MAC addresses were, and if they did find one, the router would reject it as a duplicate device on the network, as that MAC would have already been allocated to an IP address.
By far the best Parental Controls are ...... the parent. Take the device away from him until he learns the rules of the house. That means removal completely not just at a designated time.
Lots of devices will show their MAC address either on a display or printed on the device. You can also use an app like Net Scan on a phone which will show you all the connected device MAC addresses and IP addresses. So long as that device is turned off then there wouldn't be a conflict.
