If you have your essays and other stuff ready to go, apply EA.
If you get rejected, it is quite unlikely that one more semester of grades or one more test sitting would have produced a different ultimate result.
If you are borderline, you’d get deferred into the RD round. So your incremental grades/scores would be seen by UVA anyway. And you’d have some early feedback from UVA that would be helpful to the rest of your process.
