To avoid disabling Zebra daemon, you can use "table-map" to choose the
routes to send to Zebra:
<http://docs.frrouting.org/en/latest/bgp.html#clicmd-table-mapROUTE-MAP-NAME>

For example:

route-map DENY_ALL deny 10
router bgp 65000 vrf private
 address-family ipv4 unicast
  table-map DENY_ALL
 exit-address-family
