Yes. In SBProcess you can load a shared library and unload it:
//------------------------------------------------------------------
/// Load a shared library into this process.
///
/// @param[in] remote_image_spec
/// The path for the shared library on the target what you want
/// to load.
///
/// @param[out] error
/// An error object that gets filled in with any errors that
/// might occur when trying to load the shared library.
///
/// @return
/// A token that represents the shared library that can be
/// later used to unload the shared library. A value of
/// LLDB_INVALID_IMAGE_TOKEN will be returned if the shared
/// library can't be opened.
//------------------------------------------------------------------
uint32_t LoadImage(lldb::SBFileSpec &remote_image_spec, lldb::SBError &error);
//------------------------------------------------------------------
/// Load a shared library into this process.
///
/// @param[in] local_image_spec
/// The file spec that points to the shared library that you
/// want to load if the library is located on the host. The
/// library will be copied over to the location specified by
/// remote_image_spec or into the current working directory with
/// the same filename if the remote_image_spec isn't specified.
///
/// @param[in] remote_image_spec
/// If local_image_spec is specified then the location where the
/// library should be copied over from the host. If
/// local_image_spec isn't specified, then the path for the
/// shared library on the target what you want to load.
///
/// @param[out] error
/// An error object that gets filled in with any errors that
/// might occur when trying to load the shared library.
///
/// @return
/// A token that represents the shared library that can be
/// later used to unload the shared library. A value of
/// LLDB_INVALID_IMAGE_TOKEN will be returned if the shared
/// library can't be opened.
//------------------------------------------------------------------
uint32_t LoadImage(const lldb::SBFileSpec &local_image_spec,
const lldb::SBFileSpec &remote_image_spec,
lldb::SBError &error);
lldb::SBError UnloadImage(uint32_t image_token);
