I Try.

when it locates the allocated IP address, something like lease_out *, it will automatically add blocked addresses

its possible ?

 :if ("." . [:find [/ip dhcp-server lease get $i comment] "lease_out"] . "."!="..") do={
    /ip firewall filter add address-list add address $i action=drop
  }
}
