You absolutely need the correct sfp. Multimode is not compatible with singlemode fiber.

I doubt any modern car with those features have a physical sim card you can remove. They are probably all using some sort of esim. On some cars the antennas can be unplugged but that depends on the specific model. If you’re unlucky, you will not even be able to remove the tracking features at all because they are integrated with other components needed to function.

With regards to the legality of that, I unfortunately cant help you there. Probably best to search for local cases or ask a local lawyer.

Your best option in probably buing a used car thats old enogh not to track you. Hope that helps a bit

Is your os installed in a vm? No gpu acceleration?
