Finland has bunkers against Russia and they are well prepared. Maybe Ukraine could get help from the EU to build new things underground where hits by Russian drones and missiles would just be hitting the ground?

Air intake would always be vulnerable, so no. Not really as a long term thing.
Bunkers are useful for surviving the initial attack, but not long term.
