Delaying Firmware Updates

We use our WiFi locks to manage a cabin over 1000 miles away. When a firmware release occurs, it automatically downloads to my locks. Once it is downloaded I can no longer manage my lock until the firmware is installed. Firmware can’t be installed unless I have a bluetooth connection from my phone. This means I need to go back to my cabin before I can add/modify user codes. First - am I correct that I can’t make any changes until the firmware is installed? I would like to be able to install via WiFi! Second - can I delay firmware download until I am at my cabin?
