I got it working, using the realtec.efi driver. It took me some time to realise that the short vendor-class versions take over the later set long ones. Commenting out previous Arch:00007 was necessary.
Now the L3420 doesn’t install anymore, but I know were to look …

match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00000";

match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00002";
