I don't know much except after .include <bsd.port.pre.mk>
.if ${PORT_OPTIONS:MNLS}
PORT_OPTIONS+=	IDN
.endif

something like that.
For the dialog UI can't do much

OPTIONS_EXCLUDE will remove NLS from the list of define options but but NLS
remain in PORT_OPTIONS.

Do force removing NLS I would have done, in master port Makefile

.include <bsd.port.pre.mk>
.if defined(MASTERDIR)
# Force removal of NLS
PORT_OPTIONS:=	${PORT_OPTIONS:NNLS}
.endif

make OPTIONS_UNSET=IPV6 should work maybe already have it in make.conf ?

make dnsmasq_UNSET=IPV6 should also work
