How to test

Add excluded-address for an interface:

set high-availability vrrp group GRP-01 address 100.64.0.5
set high-availability vrrp group GRP-01 address 192.0.2.5
set high-availability vrrp group GRP-01 excluded-address 100.64.0.5
set high-availability vrrp group GRP-01 excluded-address 192.0.2.201
set high-availability vrrp group GRP-01 excluded-address 192.0.2.202 interface 'dum2'
set high-availability vrrp group GRP-01 excluded-address 192.0.2.203 interface 'dum3'
set high-availability vrrp group GRP-01 excluded-address 192.0.2.222/24
set high-availability vrrp group GRP-01 interface 'eth1'
set high-availability vrrp group GRP-01 vrid '123'

Check that address is assigned by Keepalived to dummy interface:

vyos@r4# show interfaces dummy 
 dummy dum2 {
