iMac 27-inch (2020) screen flickering after macOS update

I’m using an iMac 27-inch (2020 model). After updating to the latest macOS version, I’m facing screen flickering issues and visual discomfort, which is affecting my regular work.

Earlier, when my system was running macOS Monterey, everything worked smoothly without any display problems. I tried downloading Monterey from the Mac App Store, but it doesn’t allow direct installation and requires approval to proceed with the downgrade.

Since I need a stable and comfortable working environment, I request permission to install macOS Monterey on my system instead of the latest macOS version.
