Would avoiding the historical Pearl Harbor losses create more chance of a negotiated solution?
Short answerPossibly, but attacks on the Philippines and Malaya would still make a negotiated settlement difficult and could preserve demands for complete defeat.
NotesAn infrastructure raid without the historical deaths and destroyed state-named battleships would have a different emotional and propaganda effect. It would not erase Japan's declaration of war or its wider offensives. The survival and subsequent actions of the Pacific Fleet could also alter campaigns in the Philippines and Malaya. Public pressure, Allied war aims, and the room for negotiation would therefore depend on the combined course of those campaigns rather than Pearl Harbor alone.
