How to get hard pixelated shadows?

I'm making a game in URP and it has a similar style to a short hike and pako 2, but when i try to make the shadows hard and low resolution the edges get filtered and look bad, here are some photos of what I'm looking for: https://ibb.co/vH7CtFK https://ibb.co/k6Q0TWS

Thanks for any help.
