Should I make the Surface Go USB Recovery Drive before or after upgrading to Windows 10 Pro while still in S-mode?

Should I do one of the following:
1. Once Surface Go is activated, create the recovery drive.
2. Once Surface Go is activated, apply the Windows 10 Pro key and then create the recovery drive.
