Laravel Nova HasOne Relationship showing "create and add another" button

Ive set up the relationship in the parent model with a HasOne relationship to the sibling table that has a foreign key for the parent model.

The child table then has a BelongsTo method to complete the circle. the relationship works as intended.

But in Nova the create and add button still shows up when creating the child entry.

Is there any trick to getting the button to not show
