Regarding multiple device-tree(dtb) on single image

I am using openwrt to build an embedded system image - and wondering whether I can add multple device tree files (dtb) in single image.

Basically, I have multiple hardwares which needs to share the single image file for all.Upgrade will happen with the single image for different hardware.

Question is, current our boot-loader code has some kind of code to "override" some important params based on hardware type.

Rather than doing aboves, i want to put multiple device tree files (dtb) and make boot loader to load / read - right dtb file and pass the params to kernel based on hardware type.

Is it possible? If so, what would be the way to do it

Thanks in advance!
