Hello,
Is there any way to have 1 specific card NOT filter on a dashboard?
Yes, you can do this by changing the interaction.
1. Edit your dashboard
2. Click the Edit Content button in the top-right corner of the cards that would be used to filter and select Change Interaction
3. On the right-side, click Apply to Selected Cards and choose the cards on your dashboard that should interact with the filter.
You'll need to do this for all the cards that a user might click on to filter other cards by.
