I found a solution for the problem. Debian bookworm has nvidia 525.147.05 as graphic driver. This driver version does not have flicker issues on my setup.
I love Pop_OS, I am not encouraging anyone to switch away from it, but in my case I wasn't able to install a different version of the nvidia driver and Pop only provides the latest one, so I saw Debian as a easy way to have an older driver version.
