That seems overly complicated. Too many levels of conversion.
The Tindie board supports DC input as well as USB-C PD input - so you could connect it directly to the 12V from the Car power socket. It should take less than 2.5A at 12V input to give 5A at 5V output.
There are other (possibly cheaper) units that will convert 12-24V to 5V 5A. Some have a USB lead on the output.
I think I've seen DC-DC converters that provide 5V 5A PD for the Pi 5 - so no config changes would be needed. But the ones I recall seeing (on AliX) weren't cheap and were bulky with heatsinks and fans. It should be possible to make something much smaller to do the job from a 12V input.
