How to make `helm-execute-persistent-action` not to follow symlink original path

I want to complete by Tab when using find-file, so I bind a function helm-execute-persistent-action to Tab like this. ;; For find-file etc. (define-key helm-read-file-map (kbd "TAB") 'helm-execute-persistent-action) ;; For helm-find-files etc. (define-key helm-find-files-map (kbd "TAB") 'helm-execute-persistent-action) This is much better for me. But there is small problem still, the function expand symlink to original path. Is there option to disable expanding symbolic link?
