You can independently modify the reverse DNS (RDNS) records through the VMmanager control panel.
Access to VMmanager is available from your personal account: go to the server card and click "Login to VMmanager."
In the VMmanager control panel, on the required server, click on the three dots to the right of it and select "Settings." Then, navigate to the "IP Addresses" section. In the "Domain" field, you can specify the RDNS record you need.
