I have never tried an AOD510 on that driver with the stock MCU. If it works without a gate resistor, it does not need one. If it does not work without one, it does need one. You are the only one who can lay hands on that particular combination of parts, you will have to figure out what it needs.

There should not be any trouble finding the AOD510 somewhere in EU, they are still in production. The Vishay 70N02 is discontinued, that one you are not likely to find in stock anywhere.
