Thank you for the clarification.
Yes, Meta Description, Open Graph Title, and Open Graph Description can be configured using dynamic data. However, Keywords are not currently supported as dynamic data.
The available dynamic variables depend on the fields you have configured in your collection. You can find the available variables listed below the corresponding input field in the SEO settings and select the appropriate variable, such as {{Meta-description}}, for the relevant field.
For reference, you can see an example here:

Please also note that the dynamic SEO option is available only on the Dynamic Content Details page, where the SEO information can be generated based on the individual item's data.
For the Dynamic Content Index page, the SEO settings work like a normal/static page, so dynamic variables cannot be used there. You would need to configure the SEO information for the index page manually.
We hope this clarifies how the dynamic SEO settings work.
