That's what the wikia said about the debuff

How to Debuff the Boss
1. S rank node F three (3) times for Hard(甲),   two  (2) times for Normal(乙), or one  (1) times for Easy(丙). [5] 2. S rank two (2) times in node P[5] 3. Four (4) air supremacy plus white text  LBAS defense from Land Base air raids[5] After triggering the debuff, the "Quest Completion Sound Effect" will play when returning from sortie.
 * Reaching node F requires a Surface Task Force containing 5+ BB(V) + 1 CV.
 * S ranks from before the 2nd start point unlock will count.
 * Using Type 0 Fighter Model 21 (Skilled) x3 + Type 2 Large-sized Flying Boat to reduce enemy aircraft in node P can help with achieving S rank.
 * In the case obtaining S rank in node P is your final requirement, the Boss will be debuffed on the same run after you obtain the 2nd S rank.
 * S ranks from before the 2nd start point unlock will count.
 * Does not include the ones from the opening of the secret node. You must get 4 new fresh.
 * Setup 3x LBAS in Air Defense mode with Interceptors/Fighters + Saiun.
