Hi,
Thanks for your question.
SP Page Builder addons are not defined in the UI—they come from addon files in the system. You can find them here:
/components/com_sppagebuilder/addons/
/plugins/sppagebuilder/
Each addon has files like:
admin.php (settings in builder)
site.php (frontend output)
⚠️ Please note, modifying these files requires coding and changes may be overwritten after updates.
You should use Custom CSS, instead of editing core files directly. If you need any help to remove it via custom CSS please let me know.
Regards 🙂
