Llama 2, the base model, does not have any content filters or alignment built in.

Llama 2 chat, the model creates by taking the Llama 2 base model and fine-tuning it with a specialised RLHF dataset, does have "filters" (pre-loaded responses more likely to be generated for certain topics and requests). In practice, on smaller models these are able to be bypassed with some prompt engineering.

I expect uncensored chat models, created on top of the uncensored Llama 2 base models, to become available in a week or two at most (from the community, obviously, not from Facebook), if there are not already some available.
