Moving or deleting HUD elements from other mods is usually not possible, but if you're on Forge/NeoForge, there's a useful mod that makes it possible to move, rotate and scale some mod HUD elements to make them better work with Spiffy.

You can probably even remove elements with that mod by simply moving them out of screen or maybe setting their scale to 0.

The mod in question is HUD Overlays Configurator and is available for MC 1.20.1 and 1.20.4!
