How to disable function keys modification

[yuntan]

I bought latest Macbook Air M2 13inch. On this device, F4, F5, F6 is mapped as spotlight, dictation, and focus mode. However, Karabiner-Elements' default setting is launchpad, keyboard brightness up, and down. I can select spotlight for F4 and dictation for F5 on Karabiner-Elements Settings, but I can't select focus mode button. Is there any way to disable function keys modification?
