ETS6 Professional License – Purchase for a User in Russia

Hello everyone, I live in Germany and would like to purchase and pay for an ETS6 Professional license with a USB dongle for an independent KNX programmer living and working in Russia. He already has a registered MyKNX account. I contacted KNX Association, but they informed me that they could not assist due to current restrictions and suggested asking the KNX Community. Does anyone know whether there is a legally permitted way to purchase and register this license for use in Russia? I would appreciate any official information or relevant contacts. Thank you for your help!
