Technically you could suppress them. In practice, it's not feasible. You
would need to have application specific rules to suppress. The more rules you
have the more performance you lose.
But I would start by questioning whether you really need to monitor reads and
writes? If a file is opened with O_WRONLY or O_RDWR, can it just be assumed
that the file was written to?
