Yes and no. People HAVE built direct DC chargers. But the bar is way higher than with AC charging. With AC all you supply is 100 to 277 volts AC and the on board charger takes care of the rest. One simple PWM signal controls it all.
With DC charging there's a lot more to do. There's more handshaking and setup. 200 to 600 to 800 volts DC must be provided, and it goes directly to each end of the long chain of batteries. Some companies are trying: Enteligent’s Solar-Powered DC-To-DC Charger Was First Introduced At The Intersolar North America In 2023. It's not clear it's real yet. Home DIY? Well you better stand on the shoulders of others.
