User blog comment:Piperpetcp/Is there any way to edit an infobox besides “infobox builder”?/@comment-44807868-20200211033553

It's not a good practice to misclassify a template, so I'd highly recommend against that solution.

You can switch to source mode without that. There's an icon of pair of square brackets located on bottom right of Infobox Builder. Clicking on it will lead to source editing.

Also, just a note for future, Special:Forum is a better suited place for seeking wiki help! :)
