You only need to deactivate the airbag when the child seat is mounted in the opposite direction. It is obstructing the inflation of the airbag and could seriously hurt the child. If mounted in the direction then all fine.

The bucket seats don’t have ISOFIX hooks, but nothing is stopping you to simply put the child seat in the bucket seat and use the seat belt as anchor.

I went through a Swiss police control like this and no objection.
