Im genuinely curious if you have had a fitting in the past?
I had a basic fitting for the irons I swing now, pretty much just to confirm that I'm within range for standard lofts and lie angles and what stiffness to use for shafts. But no, I haven't been fit for a driver. My coach suggested it, but I haven't taken him up on it. Will probably get a basic fitting for whatever driver I end up buying next.
