How to remove all signatures from zonefile (inline signing trouble after upgrading to 9.20)

Hi Team

Of course I was also hit in the face be the inline-signing change when
using dnssec policies.

https://kb.isc.org/docs/bind-920-changes#runtime-configuration

resulting in broken validation chains etc.

I would like to start over with the affected signed zones.

I made sure to commit all changes back to the file with rndc sync -clean

And now I would like to start over by removing all signatures from the
zone file and properly use inline-signing=yes with unsigned base files.

dnssec-signzone can remove -Q inactive key or -R unpublished keys

But I found no option to remove all signatures. How do I get to a
pristine zone file without dnssec from a file with signatures?

Mit freundlichen Grüssen
