Read/Write call interaction w/ UBC

I am writing a file system that does not support caching. I wanted to know, If by just passing
NO_CACHE and CANT_CACHE option, I can disable entire caching ?

As of my understanding, the options are just to disable name lookup etc caching and it cannot
disable file content caching i.e where UBC comes into play. Can I disable file content caching i.e UBC ? (set it to UBC_INFO_NULL ?).

Also, apple docs says that UBC for apple is different from FreeBSD. I wanted to know in what respect ?
