There is some. It's extremely difficult to pin this kind of thing down, unfortunately. https://www.researchgate.net/publication/311595274_The_Roehampton_Annual_Computing_Education_Report_2015_data_from_England https://www.researchgate.net/publication/311595274_The_Roeha... for example covers how gendered schools specifically tackle this, and though most students don't go to gendered schools it's still indicative. There's other pieces here and there, but nothing conclusively stating "this is why there's a gender gap". >Otherwise, my main point still stands that there are other factors in play during adulthood, besides systematic bias There are definitely other factors in play - that's my point - and I don't think we can say it's inherent to the gender. Women being under-represented in STEM is actually a very western thing, most pronounced in the US and UK, and is significantly _less_ pronounced in many other countries. We don't know precisely why, but we do know the answer needs to be complicated and is unlikely to be "women are just naturally predisposed against science, but only in these countries."
