There currently is no official way to do that. This is mainly because
codeflow taking advantage of explicit rollbacks is almost invariably a
design mistake.

However in the interest of completeness and for better compatibility 
with suboptimal logic I am willing to accept a patch for an ->inactivate 
method (or for even more completeness an inactive() getter/setter), 
which will set the proper internal state to skip what it needs to skip.

I am not willing to add a ->rollback method to the guard though, for the 
reason stated earlier.

Patches as pull reqs here git at github.com:dbsrgits/dbix-class.git or 
email the list.

Cheers
