IPFW IPFW NAT

If I have multiple NAT configurations is there a way to delete one of these configurations without affecting the other?
I know the rule(s) directing packets to a particular configuration can be deleted but can the configuration itsself be removed?
 
Let's try...

Code:
# cu -l /dev/nmdm2B
login: root
FreeBSD 14.2-STABLE (GENERIC) stable/14-n270853-d6552ebf26bc
# kldload ipfw
ipfw2 (+ipv6) initialized, divert loadable, nat loadable, default to deny, logging disabled
# kldload ipfw_nat
# ipfw nat show config
# ipfw nat 1 config same_ports unreg_only deny_in if vtnet0
ipfw nat 1 config if vtnet0 deny_in same_ports unreg_only
# ipfw nat show config
ipfw nat 1 config if vtnet0 deny_in same_ports unreg_only
# ipfw nat delete 1
# ipfw nat show config
#
