Is it possible to exclude certain products from being affected by “Regenerate All”?

At present, “Regenerate All” applies to all visible, selected products. If you want to exclude certain items:

• Deselect them manually
  

• Use filters (by collection or title)
  

• Apply generation only to the checked items
  

Granular rule-based exclusions (e.g., exclude based on tags or SKU) are under development.
