Hi Serge,
If you are sure what you need is the card form, please refer to #1, otherwise #2.
1. We will change the fields of Details section in the Opportunity card form.
Go to Settings > Customizations > Customize the System, expand Entities > Opportunity > Forms, edit the card form.

We need to change fields of Details section.

2. The picture you showed is not a Card form.
To change the information in it, just move the first three columns of All Opportunity view.
Only the first three columns of the view will be displayed on the view you provide.
