There's no API for this particular operation.  You'll have to read the source 
of repoze.bfg.configuration.Configurator and undo what the ZCML directive does 
"by hand" as a ZCA operation.  This might work (it's untested):

from repoze.bfg.interfaces import IAuthenticationPolicy
from repoze.bfg.interfaces import IAuthorizationPolicy

But this isn't guaranteed to work between releases and will almost certainly 
break at some point.

It's probably better to just make three ZCML files: one with your 
non-authentication policy registrations, one with your authentication policy 
registrations, and one that includes both of the other files.  Then in 
production use the one that includes both of the other files, but in this other 
mode, use the ZCML file that contains everything except the authentication 
policy statements.

Even better, just leave the authentication policy registrations out of ZCML 
altogether and always pass the authentication and authorization policies to the 
Configurator constructor instead:

config = Configurator(authentication_policy=..., authorization_policy=...)
