What documentation says that Limit doesn't exist?  The Limit method is a
fundamental part of DBIx::SearchBuilder and RT.

$CustomFields->Limit(
    FIELD    => 'Name',
    OPERATOR => '!=',
    VALUE    => 'Foo',
);

There's no API to "remove" an object from a DBIx::SearchBuilder
collection; you should instead limit your search so it isn't found.
