According to their list online NO it is unfortunately not yet supported unless the list is not updated. Best bet is to ask ASUS support to be sure.
You can watch their list too. I hate the way they do their support lists as they don't link to them from their product page making it difficult for users to find.
Here is the page to watch: https://www.asus.com/us/Motherboards/TUF-B450M-PLUS-GAMING/HelpDesk_CPU/
