Suppress notification "Your dashboard was updated" on specific user accounts or devices

Hi, I am constantly working on improving my HA dashboard. Every time I change anything all dashboard devices (tablets) show the notification "Your dashboards was updated. Refresh to see changes? + Refresh button
How can I suppress this message for either specific fully browser tablets or for specific users?

This message is a part of “notification-manager”.
If someone will find a way how to access this element (particularly - some class inside “ha-toast”) and then set “display: none” conditionally…
It is NOT possible by card-mod-theme & may be is possible by an external js.
