Feature Request: Block VPN apps and software before the connection gets established

Dear ControlD Team,
I hope you are very well and satisfied. The ControlD has very good features that suit me and my home network. I have a problem which is the VPN apps and software can connect and this allows to bypass the ControlD and the settings which I configured. I know there is a feature called "VPN & DNS" and it is active on my plan, but it is only blocks access to VPN and DNS domains/websites. In other words, any VPN app like "Psiphon" can connect and establish the connection. I need a way or feature to block VPN/Tunnel connections before the VPN/Tunnel established. I know it is a very hard way because some apps uses the HTTPS/443 or DNS-Over-TLS/853 to bypass. I think the advanced firewall hardware with Deep Packet Inspection (DPI) feature can solve this problem. I know it is not something difficult for the ControlD Team. I wish such feature exists in future so it will help me to continue my paid plan.
Thanks in advance and sorry for writing too long.
