Gerry,
You power off the radio by unplugging the power. According to
this post from Farhan, there is no data being written to the SD card and the radio can be powered down by unplugging the power. If you are connected to an external HDMI display, you can shutdown the Pi from the logout option on the start menu.

Although we haven't used an external ethernet hub to connect the zBitx to the internet, this should work as long as the Pi is able to access the internet.?

Please have a look at for instructions on how to update the zBitx. You will need to connect the zBitx to the internet and plug in an external HDMI display, keyboard, and mouse to the zBitx to update the rig. To update the firmware, you will need to connect the radio to a PC using the supplied microUSB cable.?

You can use the built in SD card copier tool on the Pi to "clone" your sd card. You can also download the image file for the sd card and burn it onto a new sd card using Balena Etcher or Raspberry Pi Imager software.
