This is exactly the functionality that the 'AUTO' line provides. Arrays that are listed in mdadm.conf will always be assembled when they are found. Arrays that are not listed may or may not be assembled depending on their metadata type and the setting of 'AUTO'. So AUTO -all will disable all auto-assemble of arrays that are not listed in mdadm.conf.
