Ignoring Triggers with State Unknown on Dashboard

[kamash]

Hello,
I need Triggers whose state changes to Unknown to not be shown on the Dashboard.

An example is the below:
A network interface has a Trigger for high packet error rate. If it faces this problem, the trigger will appear in the Dashboard normally.
If the above network interface is not discovered anymore while the above trigger was in the problem state, then the Trigger state will change to "Unknown" but it will keep showing in the dashboard until the "Keep lost resources period" in the Discovery rule passes which will delete the item on which the trigger is based.
Based on the above, is there an option to immediately not show the trigger in the Dashboard after its state changes to "Unknown"?
Thank you.

I also I'm interested in a solution for this. I love the discovery feature but unfortunately my company changes ports/port names to often. It would be nice to exclude items that haven't been discovered in the last 2-4 days from a dashboard widget.

Wonder what your Zabbix version, because I'm confused... when my triggers (Zabbix 4.2.6) are Unknown the status of hosts/triggers on dashboard are OK. How your dashboards are configured?
Maybe you are talking about labels and macros? https://support.zabbix.com/browse/ZBX-15954

Zabbix Version: 4.4.1
I'm talking about the "Problems" section of the dashboard like I mentioned (The default one with no customizations). In this section, it shows problematic triggers.
I just need a trigger which has a problem (and thus showing on the dashboard) but is currently in the unknown state not to be shown at all in the dashboard at all.

The above has nothing to do with labels, macros, or the hosts themselves.

Whom should I contact to get further info about this?
