Front Disc rub from flex

Presently building up my gravel bike and having an issue. I have a flat mount Spyre on a full carbon fork, bolt through, and Mavic 650b wheels with some tyres that come up 50mm or so. All fine so far. I set the front brake up and it has decent pad clearance but enough bite by cable standards to have some stopping power. ANY flex through the bike or tilting it off axis slightly I get disc rub, straight line it is fine. I can see daylight between disc and pad both sides when I look at it. Is there anything I can do? Or is this just the result of Mavic designing a 24 spoke "gravel" wheel? I don't weigh much, about 70kg. 160 rotor - adapter set to 160 orientation.

Shouldn’t really matter how many spokes you have as the disc is attached to the hub which is fastened to your frame

In my head at least. Real world results may differ

I mean, you are right. It's annoying.

Almost impossible for it to be the hub or wheel. Sounds like a poorly made fork. Simply not stiff enough. I imagine the handling at the front is pretty poor and the alleged flex would explain why.
