If only it was that simple. In my experience (with four step kids aging from 23 down to 16, and I've been in that position for over 13 years), I'd say my input has had maybe 5-10% influence, if that.
If they're not interested in that area (and mine aren't), then there's not much you can do, even if you spend a lot of time and effort trying.
The "agency" that is dominated by the influence of their peers, schooling, and media you allow them to consume as impressionable and innocent individuals.
Normally I'd say let them grow, have their own agency and learn the world in their own eyes with parental supervision. But right now, the media and culture are so highly toxic and degenerate, that I say it's our duty as parents (and humans) to shield them from that, and instilling positive values.
