Among the youth I don’t think so. Would love to see some studies. I am sure of the disparity in views between generations. Medical science is advancing faster and well beyond when boomers only had to deal with the assault on gender constructs in clothing and hair length.1
Do you think this is top down? Who is the driver?

The title itself seems to both beg the question and exist as a tautology.
It's an interesting way to ask the question.
I think the role of academia is huge, especially their indirect role via media. A bunch of journalism majors head off to college and get indoctrinated, and end up writing style guides for newspapers that say to use "women" in ways other than the biological. People go along because they don't want to be seen as the bad guys.
Also, the political parties themselves drive division, some of which involves the trans agenda. Politically active people tend to be more ideologically driven that people who aren't so active. That tends to mean that the parties are more extreme than the average citizen, so in this case Democratic leaders do not want to alienate their base, so they support the trans agenda. The Republicans do the same, so they don't want any compromise, so they promote an anti-trans agenda. The people in the middle end up having to pick a side.
For a while, in America, the libertarian streak prevailed, and the anti-trans side was seeing the traditionalists as telling people what to do. I think the trans rights movement was riding the coattails of the gay rights agenda, which was pretty popular, especially among youth. Meanwhile, though, I think people didn't really pay attention to what was going on, and woke up to find people with penises in the girls' locker room or on girls' sports teams, and are now standing up and demanding some answers. They thought they were promoting the right to have a sex change operation if you wanted to. They are finding out now it's something different.
As a result, you're seeing the beginnings of the backlash. Lia Thomas is wildly unpopular outside of media circles. The trans rights lobbies are bemoaning setbacks in legislatures. Those setbacks aren't some weird change or heart. What's happening is that people got the memo about what is being asked for, and they are saying no.
At least, that's my take on where things are right now. It is, indeed, the youth that will matter in this, and I, too, would love to see more information, but it's hard to gather, and it just seems to me the media isn't all that keen to present it. That fact alone makes me think that maybe the traditionalists are a lot more present than the progressives on this issue. I think if the majority of high school students were supportive of males in the girls' locker rooms, the news would feature an awful lot of coverage of students supporting males in the girls' locker room. I don't see it, so I suspect it isn't there.
For my part, if you are right, and that comes out, that the youth support trans inclusion in private spaces, I'll go along. I've said that my position is based on supporting the wishes for privacy for women and girls. If you convince me that most of them don't want it, I'll change my position.
(Similarly for sports fairness.)
