Sure it can be replaced but I’ve got no idea if you can find the part anywhere around, nor if the part is somehow paired to the Mac through the infamous T2 chip, maybe @danj already has some insight about it. Technically speaking there are no guides around yet, but connectors from the few teardown pictures remind me the one of Macbook A1534, thin and delicate flat cables easy to tear if one has no previous experience. Say goodbye to the good old days,easy repairs don’t belong to Apple world anymore. If you want to get a peak to the teardown to get an idea here’s the link:
