From Rust docs:

It's important to understand that unsafe doesn't turn off the borrow checker or disable any other of Rust's safety checks: if you use a reference in unsafe code, it will still be checked. The unsafe keyword only gives you access to these four features that are then not checked by the compiler for memory safety.

One of those four features is dereferencing pointers, and unlike references, pointers are not checked by the borrow checker. So you could bypass the borrow checker using unsafe code in a way, though most probably you should not.
