I think the easiest solution is to replace Netplan by ifupdown(2) or systemd-networkd. That said, ifupdown2's "ifreload -a" leaves all interface untouched, unless you changed anything regarding this interface. If, for example, an interface eth0 has IP address X, managed by ifupdown2, and your cluster (Pacemaker or Keepalived) adds a virtual IP address Y to the same interface, as soon as you change the IP address X to Z in /etc/network/interface (or do any other modification to the eth0 interface there), "ifreload -a" will rearrange eth0, thus deleting the VIP Y. But this is better than Netplan dropping unrelated interface configurations.
