8 – Force field “location” in layout_builder

I’m using layout_builder and have a node bundle that allows for layout customization per entity.

Right now, I have a default layout that places a few fields on the page. The problem is, users can then move these fields to the top or middle of the page, or remove these fields entirely, and I actually want to FORCE some fields on the page. So for example, if my node has a disclosure that I always want at the bottom of the page and really, I don’t want someone removing it at all… any suggestions for how to do this?
