# Description:
# This function disables several kernel configuration options such as module compression, module signing,
# and automatic versioning to speed up the build process and ensure compatibility with Armbian requirements.
# It forces EXPERT mode (EXPERT=y) to ensure hidden configurations are visible and applies different module
# compression settings based on the kernel version. All modifications are only performed if the .config file exists.
