Hi all. Question about Emacs config.

I use straight.el to manage packages. I also use use-package for configuration. I have use-package configured to use straight.el. I'm using the development version org-mode, which was fantastic, until Emacs 28 started shipping with v9.5, which is all I need. The built-in version seems to load much quicker than the one I have. (I'm not byte compiling my init files; maybe I should do that?) Is there a way to make use-package use the built-in version of org-mode even though I've got straight-use-package-by-default set to t?
