Performance problems with HDRP, are there any helpful settings?

Hey, I have the following problem. I have looked at the performance in the profiler and noticed there are regular intervals peaks at the CPU. At these moments, the GPU seems to be going against zero as well as the Rendering and the Memory etc..

I made a Deep Profile on a Build Version of the Game and noticed that the problems seems to be something with the HDRenderPipline I am using. I looked up the problem but couldt find a solution. Some extra information: This is just the profile of my menu scene so there isn't much going on in the scene just a few assets, buttons and shaders. I am using 2021.2.7f1 and the the HDRP version 12.1.2. Are there any options I can change at the HDRP? It doesn't seem to be a problem with my scripts etc. Thanks for helping me out.
