Advantage use while rolling for initiative (other than determining order)?

I've only got the beginner game and was wondering if the Beta books covered the following query:

I understand that advantage on an initiative roll count towards your order. So obviously a two success, one advantage roll (2.1) beats a 2 success, no advantage roll (2.0).

What I'm wondering is that after the order has been determined, do players still get to use the advantages gained from the initiative roll on things like adding a boost die etc?

Any help would be much appreciated. Thanks in advance!

No, it just helps determine your initiative order.
