To disable that you could just do:

(define-minor-mode disable-mouse-mode
  "A minor-mode that disables all mouse keybinds."
  :global t
  :lighter " 🐭"
  :keymap (make-sparse-keymap))

(dolist (type '(mouse down-mouse drag-mouse
                      double-mouse triple-mouse))
  (dolist (prefix '("" C- M- S- M-S- C-M- C-S- C-M-S-))
    ;; Yes, I actually HAD to go up to 7 here.
    (dotimes (n 7)
      (let ((k (format "%s%s-%s" prefix type n)))
        (define-key disable-mouse-mode-map
          (vector (intern k)) #'ignore)))))

(disable-mouse-mode 1)
