I drank 17 beers and it will be about 100 hours till my next EtG am I OK?

With 100 hours passed, you will likely pass the test.

Thank you I guess it is actually going to be 120 hours is there anything else I can do to help get it out of my system?

No one here can help you circumvent the system by assisting you in clearing your system for a test.

An ETG can detect alcohol within a 3-5 day span and there is nothing you can do to alter the results at this point. 100 hours you are likely sunk, 120 hours likely pass but maybe not since you are right on the edge or the test parameter and 17 beers is a lot. I doesn't matter at this point because you can't change it now.
