Sorry I am a bit confused what you want to do.

If you have actual CXL memory installed, that means you want to use that?

But if you want to use CXL memory, you cannot disable CXL_ACPI IIUC.

If you don't want to use CXL memory in your deployment then you can either
disable CXL memory in your BIOS or, with this patch, disable CXL_ACPI in
your kernel.
