Shadows and terrible FPS drop

Hi. I’m having a problem with terrible FPS drops in my game caused by shadows. I tried to optimize them somehow so that the fps wouldn’t drop so much, but I don’t know what to do anymore. I checked some tutorials and information on the internet about it, set some options in Unity, but the FPS still drops a lot. As far as I know, there’s not much you can do about it because it’s Unity’s fault, but I’m asking anyway, does anyone know how to make shadows not take up so much FPS?

I will also mention that I use URP and FPS drops are in the range of 80 - 120 FPS
