HA support in Yandex Cloud environment

[jinxray]

There is a goal to achieve HA setup in cloud infrastructure. Following this guide, I need a dedicated interface to organize sync and high availability between opnsense firewalls. There is some limitations in Yandex cloud: https://yandex.cloud/en/docs/vpc/concepts/network-overview#limits
Including:

2.3. Network protocols that require a single virtual IP address (VIP) across VMs, such as HSRP, VRRP, or GLBP, are not supported.

There is also no functionality to create virtual interface(only binded to specific network)
Am I getting this right, that its impossible to provide HA architecture? Also, it will not be able to sync firewall config and other states

It would be nice, if someone can approve my thoughts :'(. Thanks
