Flickering white specs on some materials. HDRP

Hello! I am facing an issue where random flickering specs of light appear on some materials. See the screen shot attached. Any help is welcome!

You can maybe use the Rendering debugger to analyze your issue: Rendering Debugger | High Definition RP | 13.0.0

Could be geometric specular aliasing if it flickers: Geometric Specular Anti-aliasing | High Definition RP | 13.0.0

Hello! I think it is the specular aliasing problem but it’s on a terrain layer. How can I fix it?
