That's weird, I already could bind them (8bitdo ultimate 2 wireless connected via Bluetooth). Gyro also works on the beta update.
The only feature missing at this point is the ability to wake up my steam deck LCD with Bluetooth :P
Edit: oh no, the update reversed the button glyphs, and if I change it to "Nintendo mode" it reverses the functionality as well lmao. Oh well, hope they change it back.
