Compute Module • Custom Device Tree Model Property

I'm working on a project that needs a custom device tree. I have a custom carrier board for the CM4 that has a lot of on board devices that needs to be configured and it doesn't make a lot of sense to use overlays for everything. I have a question about the top level model property. If I override that, I still see this in the output from dmesg:

Code:

Machine model: Raspberry Pi Compute Module 4 Rev 1.1
I also see the model property still being set to that when I dump the device tree using:

Code:

dtc -I fs /sys/firmware/devicetree/base
Is the bootloader overriding what I put into the model property? I see other changes I've made to the device tree, including my addition to the compatible property. I'm fairly certain that my device tree is being loaded. Is there any way that I can tell the bootloader not to override the model property?
