See https://github.com/siemens/meta-iot2000/issues/96 for the complications. There are also link to an external layer that tried that, but I didn't follow in details if it turned out to be truly successful in the end.

That can happen via the meta-iot2000 layer, thus on a developer workstation. But all those integrations and adjustments are tasks which require prior experience with the Yocto build system and workflows.
