I have done soemthing like this before:

(setq org-latex-minted-options
           '(("frame" "lines")
             ("fontsize" "\\scriptsize")))

;; custom code block format to indicate input variables
(defun my-src-block (src-block contents info)
  (cond
   ((eq (elt (plist-get info :back-end) 2) 'latex)
    (concat
     "\\begin{tcolorbox}
"
     (format
      (concat
       (when (org-element-property :name src-block)
(format "src block name: %s\\\\" (org-element-property :name src-block)))
       "language: %s")
      (org-element-property :language src-block))
     (org-latex-src-block src-block contents info)
"
\\end{tcolorbox}"))))

;; custom exporter
(org-export-define-derived-backend 'my-latex 'latex
  :translate-alist '((src-block . my-src-block)))

(org-export-to-file 'my-latex "manuscript.tex" nil nil nil nil nil)
(ox-manuscript-latex-pdf-process "manuscript.tex")
