Block unknown devices on Deco M9 - user changes MAC address to fool parental controls

Hi all,
I've been using the Deco M9 Plus for a couple of days now and I'm very pleased with it. The wi-fi is excellent in whole our house. And especially the parental controls are very valuable too to control the extensive use of internet of some of the users.
I have a question however. Is there an option to (automatically) block unknown devices on the network? I'm familiar with the blacklist option but I wouild like to see a whitelist for devices as well. The problem is that one user in our home is smartass enough to change the MAC address of his computer each time the parental control blocks his internet. Ofcourse the Deco notifies me that a new device is noticed on the network and than I can manually block the device but is there anyway it can be done automatically?
The Deco acts like a router and is directly connected to my ISP modem.
Is there any other option to block unknown MAC addresses from the internet should there be no possibility to achieve this with the Deco?
Thanks for your replies.

Is this a joke? You've been registered here for a couple of weeks and you're jumping in to a 6 year discussion with irrelevant suggestions.
A) The linked article does nothing to address the parental control shortcomings discussed over the course of the last 6 years in this thread. Had you read both you would realise this.
B) People in this 6 year saga have repeatedly reached out to the "technical" team, who simply do not provide any solutions.
C) I, along with many others, have now abandoned TP-Link products due to the shortcomings and lack of support. I only remain subscribed to this thread out of morbid curiosity and for the comedy value of "advice" like yours.
Thanks!

@EDuff Since this thread opened my kids have grown up, and left home, so it is no longer a problem for this grandad.
I'm sorry, to any new parents buying TP-Link for " P A R E N T A L Control " ....

I am not saying you are wrong but I think that you should also get a very good brand which has always helped people.
A TP-Link Wi-Fi extender can really help improve your home or office network in several ways. Here’s why it’s worth considering:
1. Extended Coverage
2. Improved Signal Strength
3. Enhanced Streaming and Gaming Experience
4. Easy Setup and Installation
5. Cost-Effective Solution
6. Supports Multiple Devices
7. Maintains Wi-Fi Speed
8. Compatibility
9. Roaming Capability
10. Security Features
