FWIW, there would be only 6 models to match if this needs to be
constrained to ones with dual GPUs:

MacBookPro11,3
MacBookPro11,5
MacBookPro13,3
MacBookPro14,3
MacBookPro15,1
MacBookPro16,1

And it seems to me that the product_name in efi_smbios_type1_record
would contain that model name.

Thanks,
