You technically can sometimes, but in my experience it's really difficult to actually do that. Dealerships get limited custom order bank allocations, and if you're not really early when the MY order bank opens your order will potentially slip a model year or even more (at least for in-demand models).

For Hyundai specifically I was looking for the Limited trim, and I've been told they're only allocating custom orders to dealerships with level 3 chargers. And even then the order bank for MY 2022 had already been closed when I started shopping around. I would have had to wait for the MY 2023 bank to open.

I've done it twice with VW for ID4s. There's no special time period to order, and you don't need to talk to a dealership first, you can order from the VW website any time. If your car doesn't go into production until after a model year rolls over, then you get that newer model year.
