Thanks for your feedback!

Indeed...
We usually use null to remove a slot rather than undefined if I recall correctly, but this is not working either.
You can pass () => null but we will see how to improve it 👍

I do this by removing components

<TreeItem2IconContainer sx={{ width: 0}} {...getIconContainerProps()}>
            <TreeItem2Icon status={status} />
          </TreeItem2IconContainer>

and set gap to Content

<TreeItem2Content  sx={{gap:0}} ...others>
