Why Operation Chariot followed bombing proposals

If Operation Chariot had not attacked St Nazaire, would Britain have tried another way to disable the Normandie Dock?

Yes; RAF bombing and offshore battleship bombardment were considered before the destroyer-and-commando raid was judged the best workable option.

A viewer asks whether the Normandie Dock would have been attacked by other means if Operation Chariot had not taken place. RAF bombing was the first choice examined, and planners also considered shelling the facility from offshore with battleship guns. Brest lacked a dry dock large enough to substitute for the St Nazaire facility. Those approaches and constraints led to the more direct but hazardous plan of delivering Campbeltown to the gate.
