ROS2 targets only 64 bits systems at the moment so there is no libraries built for 32 bits system.
You could try to build the ROS 2 stack from source in 32bits, but as we never tried it you may face several challenges along the way.
In the future please ask your questions on ROS Answers following our support policy and tag your question with the ros2 tag.
Update: Answered in the duplicate question on answers.ros.org.
