No Bluetooth, ASUS Strix G15 Advantage Edition

Hello Manjaro Community,

no Bluetooth is detected with the ROG Strix G15 Advantage Edition G513QY 2021.
Using Linux kernel 5.13.12-1 and 5.14.rc6 with KDE plasma 5.22.
What could be the reason for this?
Does ASUS have certain key combinations on the keyboard to enable Bluetooth? So far I always had notebooks from Acer and HP with which Bluetooth always worked.
Bluetooth is also not recognized with Windows 10.

Thanks for Help!
