I think that the attached patch should be applied to
doc/lispref/display.texi, looking at the actual usage of `disable-eval'
in lisp/textmodes/enriched.el and src/xdisp.c:
,---- enriched.el
| (defun enriched-decode-display-prop (start end &optional param)
| [...]
|     (if enriched-allow-eval-in-display-props
|         (list start end 'display prop)
|       (list start end 'display (list 'disable-eval prop)))))
`----
,---- xdisp.c
| handle_display_spec (struct it *it, Lisp_Object spec, Lisp_Object object,
| [...]
|   /* Support (disable-eval PROP) which is used by enriched.el.  */
|   if (CONSP (spec) && EQ (XCAR (spec), Qdisable_eval))
|     {
|       enable_eval = false;
|       spec = CONSP (XCDR (spec)) ? XCAR (XCDR (spec)) : Qnil;
|     }
`----
