Notice their natural interests and try to apply your adult brain to getting them access to more resources to explore and practice those interests.
Aim without hoping to get there, at zero screen time.
Actively personally participate in their interests with them.
Search out and try new hobbies and activities for them to get exposure to.
Make most things optional, but make adult decisions about things that they must continue to do even if they don’t much like it.
Turn off that TV.
Demonstrate curiosity. Kids are interested in things things their parents are interested in. I don't watch sports - my kids are not interested either: we signed them up for soccer, but they are just running around with no clue why it is important to kick the ball into the right net.
