May I submit my accomplished OAVF No. 1 and submit myself for live capture of my biometrics on different days?

No, you may not.  The accomplished OAVF No.1 must be turned in on the same day that you intend to have your biometrics taken because even if you have submitted in your OAVF No.1 but have not had your biometrics taken, your application will still be deemed NOT FILED
