Would Japan arm its bombers differently against a carrier?

Knowing Force Z had a carrier, would the Japanese bombers carry their full defensive armament?

They might carry more guns on a shorter-range mission, but the added weight could not substitute for fighter escort against Indomitable's directed fighters.

Japanese intelligence would know a carrier was present, but the historical aircraft shed weight because the search and strike demanded extreme range. They already expected some possibility of meeting fighters from Singapore, although those fighters would be near their own endurance limits. A shorter approach could permit more defensive armament. The bombers also lacked armor and self-sealing tanks, leaving them vulnerable even if some guns were restored. They would still lack escort and remain exposed to a coordinated combat air patrol, so extra guns would probably increase the cost of interception without changing the basic outcome.
