Sync acme cert between two vyos instance

Hello
If we want to run an sstp server on two different servers, how can we properly organize certificate synchronization between servers if use acme?
Example router A has config

set pki certificate vpn acme domain-name ‘vpn.somedomain’

When sync config work this line will be duplicated on router B, but the certificates will remain on the router A.

You should probably organise something manual with the task-scheduler option, scp the certs over every 24 hours or similar.
