If it is not shown, probable nothing or default.
Best to set it to what you need so you are sure what's there.
I assume WPA2 and WPA3 ?
No encryption (only use it if you know why and you're sure your devices support it) ?
I still don't see a manual frequency selection ?
It might be a bit more visible in Winbox/Webfig.
Use this as base for guidance.
https://help.mikrotik.com/docs/display/ ... figuration:
First define your channels (frequency and band) you will use.
Then security settings
From there you build a configuration
And then apply that configuration to the radio.
But it can also all be done on the radio itself, that will have priority then
As a reference, my (redacted) setup on AX3:
