From what I know is that you need to create those things yourself.
For your interest please visit the wiki for the config /etc/config/wireless
As you can see you can specify option wpa_psk_file '<path of the file you need to create yourself'
The path is a file you can create which specifies further the vlan data and mac wildcard.
There is also an less documented one and very recent:
sae_password_file
Honestly I don't know much about this one.
There is also wifi-vlan and wifi-station which are newer config variations which do the same as the wpa_psk_file.
Note for wpa_psk_file you need wpa2, depending how far this OpenWrt version goes you may be able to use wpa3, but it is required to use macs and in very recent OpenWrts it also has been turned into a list for wifi-station, I would advise to stay on wpa2 for now also because of config stanza changes which could put you in more work for nothing, WPA2 is the only one which does not enforce the requirement of listing client mac addresses to a vlan password, WPA3 is and that is according the specification.
The problem with this version of OP24 is that it isn't the most newest version of OP24 from the gl firmware, the last direct OpenWrt is op25 which there is no gl firmware for.
I wrote a cli command script for wifi-station and wifi-vlan.
Personally wifi-station and wifi-vlans are better because these automatically get preserved when upgrading firmware when keeping the settings, when using wpa_psk_file the file location does not get preseverd but it is possible by adding it to /etc/sysupgrade.conf so it gets tracked.
