I dug a little deeper by going through the code. I don’t think this is documented, but reading the code, I have realized that you can use a function name instead of a string. So this below works. (If you are interested in where to look, it’s function `org-roam-capture--fill-template`).

         :target (file+head+olp my/get-note-file-name ;; <= file name
                                my/get-tech-head ;; <= head (only once for file)
                                ("Note")) ;; H1
         :unnarrowed t)))

(defun my/get-note-file-name ()
  (with-temp-buffer
    (insert-file "~/Documents/temp/filename.org")
    (buffer-substring-no-properties (point-min) (point-max))))

(defun my/get-tech-head ()
  (with-temp-buffer
    (insert-file "~/Documents/temp/head.org")
    (buffer-substring-no-properties (point-min) (point-max))))

```
