I am using Obsidian Bartender to do what you want to do: GitHub - nothingislost/obsidian-bartender: Allows for rearranging the elements in the status bar and sidebar ribbon
It offers a custom sort option to the File Explorer that allows drag and drop sorting.
Also see this thread: File Explorer Custom Sort - #119 by JohJoh. Obsidian Bartender comes up near the end.
Obsidian Bartender is not yet available in the Community Plugins so it is a little more work to install at this time.
