Amazfit Watch faces

Hi!

Does anyone know if there is any way to manually turn off the bluetooth connection on the Amazfit Bip? If not, is it likely that this will be an available option in a future update of the firmware?

I wrote to Amazfit many times asking for this feature.
I sleep with the watch (and often with my hand under the pillow) so I would like to disable bluetooth.
Amazfit Verge has that feature (you can schedule it too).
