raspi-config [nonintoptions_]

raspi-config is the official configuration utility for Raspberry Pi running Raspberry Pi OS. It provides an ncurses-based menu interface for common system settings.
Configuration options include network settings, display options, interface enabling (SSH, VNC, SPI, I2C), performance tuning, localization, and system updates. Many settings that would require manual file editing are accessible through this tool.
