Hide the Scoreboard and Bossbar
Access the Overlay Settings
Open your mod configuration menu (usually accessible via the mod menu or by pressing a designated key). Look for the Enhanced Overlay settings panel.
Disable Scoreboard Display
Find the Scoreboard section in the settings. Toggle the option to hide or disable the scoreboard rendering. You can also customize its position and scale if you want to keep it visible but adjust its appearance.
Hide the Bossbar
Locate the Bossbar or Boss Health Bar option in the same menu. Disable it to remove the health bar that appears when you're fighting bosses or other entities.
Apply Changes
Save your configuration. The scoreboard and bossbar should no longer appear on your screen during gameplay. If you want to re-enable them later, simply return to the settings and toggle them back on.
Tips
You can customize other overlays at the same time—consider hiding the player tab list or adjusting chat transparency while you're in the settings menu for a cleaner overall screen experience.
