There is this document https://datasheets.raspberrypi.com/debu ... cation.pdf which outlines the pinout when used with side-entry or top-entry connector.
As there are no free pins on the CM5 connectors the UART connector footprint got added to the module. CM5 datasheet - page 17, 2.23 has the info.
See also here viewtopic.php?p=2272792&hilit=Debug+uart+cm5#p2272595 where I've raised that question shortly after the CM5 launch.
A custom cooler would be the easiest solution from my POV. As CM5 is targetting commercial uses I doubt that many of them will need the debug UART.
You may still use GPIO14/15 as long as your not interrested in the early stage bootloader log.
