How to connect to wifi from a PC with a specific mac address?

Question

User identification

Installed controller for UniFi access points. At the moment, authentication occurs using RADIUS.
There are some devices (5 pieces out of 200) on which I would like to connect to access points without a password, or only one unique login-password pair (only on these 5 devices). Is it possible to implement this, if possible, tell me in which direction to drip. As an option, I considered creating a network with a different name and letting it whitelist for mac addresses there.
