since version >= 30.2, not yet installed pkgs' brief introductions consult, especially like pkg in melpa

[EssenSea]

since emacs version, load package.el and straight.el simultaneously while caused error warning.
That's means (setq package-archives '(("melpa" ....))) while raise this warning.
whether there is some way to consult brief introductions about yet uninstalled pkg inside emacs without raise the error warning?
