Hi Frank,
Thank you for reaching out.
Yes, you can uninstall EasyStore without affecting SP Page Builder, provided that your pages are not using any EasyStore-specific elements or integrations.
As a precaution, we strongly recommend taking a full backup of your website (both files and database) before proceeding with the uninstallation. This will allow you to restore the site easily if anything unexpected occurs.
If you encounter any issues during the uninstallation process, please let us know, and we'll be happy to assist you.
Best regard
