I don't see how to realize the issue by using 'advise' but you could
use a new function which does it.

Put the code

--8<---------------cut here---------------start------------->8---
(defun org-agenda-switch-to-in-other-window (&optional delete-other-windows)
  "Go to the Org mode file which contains the item at point in other window.
When optional argument DELETE-OTHER-WINDOWS is non-nil, the
displayed Org file fills the frame."
  (interactive)
  (if (and org-return-follows-link
	   (not (org-get-at-bol 'org-marker))
	   (org-in-regexp org-bracket-link-regexp))
      (org-open-link-from-string (match-string 0))
    (let* ((marker (or (org-get-at-bol 'org-marker)
		       (org-agenda-error)))
	   (buffer (marker-buffer marker))
	   (pos (marker-position marker)))
      (unless buffer (user-error "Trying to switch to non-existent buffer"))
      (switch-to-buffer-other-window buffer)
      (when delete-other-windows (delete-other-windows))
      (widen)
      (goto-char pos)
      (when (derived-mode-p 'org-mode)
	(org-show-context 'agenda)
	(run-hooks 'org-agenda-after-show-hook)))))

(org-defkey org-agenda-mode-map "\C-u\C-m" #'org-agenda-switch-to-in-other-window)
--8<---------------cut here---------------end--------------->8---

into your emacs init file to get the the behavior you want with the key
C-u RET.

The function above is almost the same as `org-agenda-switch-to' which is
currently bound to RET in org agenda.
