Currently NO.
OpenVINO 2020.3 LTS doesn’t support Ubuntu 20.04. As a result, we support ROS2 Foxy in ROS2_OpenVINO_toolkit repo by compiling Foxy from source code onto Ubuntu 18.04.
OpenVINO 2021.x supports Ubuntu20.04, so we are still in progress of porting OpenVINO 2021.x versions to ROS2_OpenVINO_Toolkit repo.
