How to disable/remove panel drop shadow in plasma style

Hi all, I have recently been trying to modify the default breeze plasma style to have a completely transparent panel and have been (mostly) successful.

The only hiccup I have found is that while setting a panel to be floating in the edit menu there is a drop shadow added as seen in the picture
I cannot figure out how to disable/remove this shadow and was wondering how or if it is possible at all. The drop shadow is not present if the panel is not floating.

I am on Plasma 6.0.4
