There is no `org-export-current-backend' in the new exporter. Besides,
what you want is the default behaviour (see `org-e-beamer-frame-level'
variable).

Filters are different from hook. A function in a hook operates on an Org
buffer. A filter function operates either on a string in output syntax
or on the parse tree.
If, for some reason, you want to modify export options "on the fly", you
could create a filter function for parse tree, and modify options plist
from it:
#+begin_src emacs-lisp
(defun my-options-change-fun (tree backend info)
(when (org-export-derived-backend-p backend 'e-beamer)
(plist-put info :with-author nil))
;; Don't forget to return tree.
tree)
(add-to-list 'org-export-filter-parse-tree-functions
'my-options-change-fun)
#+end_src
