What desired graphical backend needs to be specified in building Yocto Project?

I'm building Yocto Project for  iMX8QXPMEK board.  What desired graphical backend do I need to specify?

5.1 Build configurations
i.MX provideds a script, fsl-setup-release.sh, that simplifies the setup for i.MX machines. To use the script, the name
of the specific machine to be built for needs to be specified as well as the desired graphical backend.

I'm using BSP Release L4.19.35_1.1.0

I specified 'Wayland' Backend

DISTRO=fsl-imx-wayland

What is the purpose of specifying backend?  Is it only needed if the embedded system has display?

Hello Amer Naseem,

The backend would refer to the display server protocol and is used only if you will be running a display server. Most often you won’t be using it unless you use a display, albeit in some cases you may want to run the display server even without a physical display so that you can connect remotely and have a graphic user interface running on the board.

I hope this helps!
