So it's easy to cut off the oxygen supply to the fire?

Sure - so long as you've spent the necessary $millions in advance, to build that feature into the ship. Plus crew training, safety certifications, insurance, etc. Imagine if a couple idiot kids or passed-out drunks were in the compartment which you de-oxygenated.

  Last time I took a big car ferry the car decks were off limits for passengers. On a smaller ferry it's more of a problem but the risks are also lower.

    Last time I took a ferry with car capabilities (between Hokkaido and Honshu) the car deck was very much accessible to passengers.

Li-ion batteries supply their own oxygen when they burn, you can't smother the fire.

There are deck walls strong enough to prevent a vehicle falling out of the ship, but usually open at either end to ensure good ventilation. There are hundreds of these ferries operating in Europe (and other places with large islands or short seas/lakes), from tiny ones that carry 2-4 cars, to large ones with multiple decks. https://www.alamy.com/stock-photo/car-ferry.html?sortBy=relevant https://www.alamy.com/stock-photo/car-ferry.html?sortBy=rele...

Note these are public passenger ferries. You arrive at the port, buy a ticket, drive on and (usually) get out of the car for the journey.

Not easy. The vehicle decks on ferries can't be tightly sealed off. Modern ferries often have CO2 fire extinguisher systems fitted but those have limited capacity and the fire can reflash quickly when the oxygen level rises again.
