Thanks for the suggestion to use view-mode. I bound a quick double-tap of vv.

    (use-package key-chord
      :init
      (key-chord-mode 1)
      ;; (key-chord-define-global "jj" #'avy-goto-word-or-subword-1)
      (key-chord-define-global "vv" #'view-mode)
      :custom (key-chord-one-key-delay 0.3))
