Supply power to Pi and to XHAT separately

Hi,
I’ve modded my Picade to have the XHAT away from the Pi, in order to fit an oversized heat sink. That’s leading to constant undervoltage warnings, apparently due to the flat cable resistance connecting them together.

As I’m already powering the display with a separate PSU, my next attempt would be to power the Pi and the XHAT separately too.
I wonder if that would work, but more importantly, I believe I have to disconnect the power going from the XHAT to the Pi. Would someone identify which pins to disconnect?

Thanks
