You are eligible for a waiver per the waiver guide, because you are an H2 due to only one frequency in one ear. You do not sign or formally request a waiver--it's all routed with or without you, unless you specifically ask to withdraw from the Recruiting process.
Your first major step is to determine which office actually disqualified you? There are several waiver middle men. AFRC/RS, AFRC/SG, or AETC/SG? Most likely it was RS (Recruiting), who is not the actual authority but they act as a gate keeper. If it was Recruiting, you can absolutely fight it.
