TL;DR you have to use the VRM
I read the OP as asking if it's possible / safe to run the radio from a PDP WAGO output instead of the VRM in a pinch, not if it's competition legal.

I personally wouldn't risk it - both sources are 12V, but the VRM is limited to 2A, whereas the PDP outputs are 20A or higher. More importantly the VRM is a regulated 12V source, whereas the PDP outputs provide a variable battery voltage. You probably wouldn't be at risk of frying it, but it would likely reboot if your battery voltage dropped for a moment.
