Phantom power over 1/4 inch?

I've been using a focusrite 2i2 (gen2) for practice at home, and a little recording for a while now. I'm currently running my pedal board into the focusrite, to get the same tonal options I get when I play through an amp, or on stage. The last pedal on my board is the Tech21 VTBass DI. I currently have it connected via a 1/4 inch cable, because that cable was the perfect length. I also have a microphone plugged into the focusrite, which requires phantom power. So now I was wondering, if the phantom power only goes through the XLR outputs, or also through the 1/4. My guess would be that it needs the three pins of the XLR to deliver any power at all, and I know that the Tech21 could also be powered through the phantom power with an XLR cable, but I already have it on my pedalboard with the pedalboard PSU connected.
Would it potentially be bad if I had the Tech21 recieve phantom power and the PSU power at the same time? I guess I was mainly hoping to just be able to keep the Tech21 plugged into the focusrite with the 1/4, without having to turn off the phantom power.

I'm not keen on doing trial and error with such an expensive pedal, even though I'm fairly certain it would be fine. The manual of the Tech21 said it only takes the phantom power via the XLR cable (makes sense), but the focusrite manual doesn't state any specifics about how the phantom power works as far as I could see.
 
I have the same setup with the Scarlett 2i2 (3rd gen) and the VT Bass DI. The phantom power is only thru XLR. If you need to power the VT Bass via a separate power source for the 1/4" connection and the phantom power is activated on the 2i2 for the mic, it shouldn't affect anything in a negative way. At least not that I can detect.
