Yes, I think the debt brake should be removed. Although one could also change the restrictions the debt brake so that it allows to take on debt for investments that lead to more growth.

The debt brake can be "disable" though, this is the case right now for COVID and Peter Bofinger has made an interesting argument that one might also be able to do this for investments to defeat climate change by declaring this is a natural disaster. Although anyone who tries that probably has to make that argument to the constitutional court.
