I don't understand, can you make an example video?

Not sure anyone here is that invested, perhaps you work with someone who can assist you?

You could bridge the R144 pads with a wire, or wire some jumper or switch.

That might work, but these H7's can be bricked quite easily to the point where serious intervention is required. Why there's not a jumper or switch perplexes me.
