UART Camera Control can give you a great amount of wireless control over your camera OSD.
It's easy to set up in current versions of betaflight but you need to ensure you wire correctly.
For the Hyperlite F4, it's important you wire the camera to UART 4 as this is the best uninverted port for camera control.
Once that's done, simply set up camera control on UART 4 under ports and you should then be able to use stick commands to access camera OSD while disarmed.
Thanks to Dan Vogel for the screenshot and the work figuring out the best config.
