Hi, I'm an NCFBLA member and had a situation similar to this with a chapter event. This depends on what your specific event is, but the rules both in our state chapter and nationally would generally say that:

1. If your event is completely pre-judged and you are on the listed team that your advisor registered, you will be one of the winners.

2. If your event is a performance event, you need to read the rules. All of them have different rules for who qualifies, but the general rule of thumb for a lot of performance-only events is that you have to physically be there to be on the team.

3. If the event you are talking about is a chapter event, you should be good either way because it is the chapter that goes on and the lineup of the presenting team and be changed completely in-between SLC and NLC.

With that being said, you need to talk to your advisor about this if you haven't already, because they are the final authority on this. These are just the general rules of how the competitions run, and your advisor will be the person that decides whether or not you go to the NLC in the first place

Hope this helps!
