Does metabolism play a role In getting alcohol out of your system?

I am on parole, and I am 5’9 100 pounds, wild I know. But I eat 2k calories a day and don’t gain any weight, I have an insanely fast metabolism. I’m just wondering If it plays a role, on how fast your body gets alcohol out. Say I have drank 24 beers within the last 72 hours, how long Is It going to take to get out, and what’s the fastest way to get It out. (I know this may not be the right sub for this, but I don’t know where else to ask) I have to do EtG tests, and they show up for 80 hours. I have at home EtG tests, but I don’t know If they are as accurate as the lab ones.
