Texture flickering (not polygon z-fighting)

Hello!

I’ve noticed these texture flickering, coming from the multiple overlayed textures in the shader (definitely not a polygon z-fighting, I checked)
the solutions I’ve found so far are made through the code and I have no idea how to do it
is there a way to fix it via shader graph?

my unity version is 2020.3.7, URP

Share your shader graph (and maybe try in the latest 2020 version?)

oh. it’s massive
I’ll try to explain, but I have a feeling it’s going to be hard to understand

I use 5 layers of tileable textures, which are blended with each other using a subgraph with different blend options like lerp, multiply, add, normal combine, slope mask, hard light blend mode etc
