Maybe the following stuff works, though I haven't test it.

(defvar my-AUCTeX-process nil)
(use-package smart-compile
  :init
  (declare-function smart-compile-string "smart-compile")
  (defun run-latexmk ()
    (when (string-match ".tex$" (buffer-file-name))
      (let ((buf (get-buffer "*Background TeX proccess*")))
        (if (bufferp buf) (kill-buffer buf))) ;; flush previous log
      (unless (and (processp my-AUCTeX-process)
                   (eq (process-status my-AUCTeX-process) 'run))
        (setq my-AUCTeX-process
              (start-process-shell-command
               "Background TeX" "*Background TeX proccess*"
               ;; use an external application as the previewer
               ;;(smart-compile-string "latexmk -pv %f")

               ;; use pdf-tools
               (smart-compile-string "latexmk %f"))))))
  (define-minor-mode AutoTeX-mode
    "Mode for compiling latex sources and creating PDFs after saving."
    :global nil
    :lighter " Auto"
    (if AutoTeX-mode
        (add-hook 'after-save-hook 'run-latexmk t t)
      (remove-hook 'after-save-hook 'run-latexmk t)))

  :hook (LaTeX-mode . (lambda () (AutoTeX-mode 1))))
