WiFi Parental controls for Private Address feature in IOS 14

I have setup parental controls for certain devices on my WiFi and all works fine on the MAC address. https://support.apple.com/en-gb/HT211227 However, in iOS 14 there is a new privacy feature which changes the MAC address every day so it is randomized. Any ideas how to ensure parental controls on WiFi is setup to handle this? Otherwise I have to update the WiFi parental controls frequently which is a non starter.
