How to set up your own DNS for each SSID?

Question

Domain Name System

Hello,
I would like to configure the router in such a way that it offers several SSIDs, and after the user joins one of them, it assigns different DNS settings depending on which SSID the user has joined. This is necessary in order to use the dns.yandex.ru settings for both adults (basic option) and children (family option). Question: how to do it? Do I need to use alternative firmware for this? What keywords to use for search?
I understand that other solutions to the parental control problem are possible, but they are all based on recognizing devices by MAC address. But this is not suitable, because guests with new devices can come to children, and you don’t want to catch new devices every time.
Thanks

On Mikrotik it is done without problems.

Each SSID needs its own DHCP settings, which will already give DNS depending on the SSID. If the current firmware does not know how to do this, but at the same time it can publish several SSIDs, you need to dig towards alternative firmware, and possibly routers.
