I tried this config too, and it doesn't work on v4 only system:

# This is rfc7706 config
# https://www.dns.icann.org/services/axfr/
auth-zone:
        name: "."
        for-downstream: no
        for-upstream: yes
        fallback-enabled: yes
        zonefile: /var/lib/unbound/root.zone
        #master: lax.xfr.dns.icann.org.
        master: 192.0.32.132
        master: 2620:0:2d0:202::132
        #master: iad.xfr.dns.icann.org.
        master: 192.0.47.132
        master: 2620:0:2830:202::132

Only after I comment out ipv6 addresses zonexfer will happen.

unbound-1.9.1 is the version I run.
