Shunt operation, signal bypss

Im sure this has been asked many times before, but is there a command i can use so my cargo trains will ignore the signal and enter a goods yard?

I'd recommend searching for driver commands by author atilabarut. You'll find a whole suite of shunting-related commands.

I find it necessary to place invisible signals at either end of each yard track. That way, the AI driver can proceed on a yellow indication when the approach junctions are lined for it. This is true as well on sidings when there is only one signal at the two junctions, e.g. Tume's Milwaukee Road Avery-Drexel.
