Blending Asset Edges

I’m relatively new to Unity - Had it for years to just play with and try tutorials, nothing ever really finished though.
I’m doing some level design, and hope there is a way to blend the edge of an asset into the ground to make it seem like it fits more naturally. I’m using Megascans assets and textures, but can’t get rid of the seam between the asset and terrain.
Is there any way to do this? I saw for UE4 Megascans basically gave a slider the feathers the edge of the asset, but didn’t see anything like that for Unity.

Even though these assets are from the same “Package” on Megascans, they don’t mesh together well and pretty obviously stick out.

Any help would be greatly appreciated

Hi,

I was experimenting with exactly the same assets!
No solution found yet, I can only tell I bought microsplat plugins from asset store, that did not worked well in hdrp, some time ago.
