[MariaDB discuss] Upgrading MariaDB 10.6.15 to 10.6.17 on Ubuntu 18.04 (unsupported)

We are currently unable to upgrade our server os from Ubuntu 18.04 to 22.04. So we are stuck on MariaDB 10.6.15 and cannot apply any subsequent minor/major releases. Is it possible to somehow use installation binary package for Focal/Jammy or worse case recompiling from source for 18.04?
