UE5 Path Tracing Still Render Issue

When using the automotive materials package for rendering, I am experiencing frosted glass and excessive noise in the output renders. The noise persists even when I disable denoising, and applying denoising afterwards leads to loss of detail.

I have extensively searched forums and YouTube for solutions but have been unable to find any effective solutions.

Is there anyone who can help me on how to achieve high-quality still renders using path tracing without losing detail?

I’m also sending the settings of my latest render.
