Test on 6.14.0-rc5-wt-ath+, with the firmware you used.
I can get 6 GHz AP and connect to it.

I can even connect to it by Ubuntu GUI.
Can you update to 6.14.0-rc5-wt-ath+ and have a retry? Also please make
sure that your wpa_supplicant/iw support 6 GHz(or directly update to the
latest version).
If you still cannot find 6 GHz AP, you can set debug_mask to 0xffffffff
to get ath12k logs. Then give it to us.
