There isn't really an automated way to convert them quickly, but it's not too hard. I've adapted two of the new drill templates to Taydas coordinate system this week. Which one(s) are you interested in?
You can open the drill template in Affinity Designer (or similar) then translate the X/Y coordinates of the center drill mark to millimeters from the center of the corresponding side.
Afterwards, for Tayda you need to invert the polarity of the Y coordinate. (eg: 100mm becomes -100mm)
