Roof mount brackets for 50" Onx6 on 2020 TRD OR?

Anyone know of any brackets available that dont involve drilling into the roof (or necessitate a roof rack which i don't want and would never use) to mount a 50" onyx 6 on a 3rd gen? I've looked extensively and haven't found anything I called @Baja Designs and actually had them look up a couple of options which they didn't thing would work because the onx6 requires two screws in the side...they just told me maybe check Rago or SDHQ, neither of which appear to offer anything useable.

Also just to note, the light bar on the roof quest is a utility situation...I often end up places where there is no trail (or at best a very ambiguous trail), and what I'm looking for is a solution to provide "very far ahead spot illumination". Was originally looking at KCs pro6 gravity (that does have a greatt mount) but want something lower profile.

TBH it seems a little shocking that there isn't a readily available option for this, but any input or suggestions would be great!
