HI @Anonymous ,
Do you want to control columns visible within the Model-Driven app List View?
If you want to control columns visible within the Model-Driven app List View, please consider take a try with the following workaround:
1. Go to Entities in your PowerApps web portal.
2. Select the Entity your Model-Driven app related to.
3. Switch to "Views" tab, then find the Entity View where you want to control the column visible.
4. Click "Edit View"-> "Edit View in new tab"

5. Then within the opening Entity View Designer, you could adjust the Entity View, and make it looks like you expected:

6. Click "Save", and then "Publish" your changes made to this Entity View.
7. Open you Model-Driven app again, the changes you made would be applied to your Model-Driven app list view.
Best regards,
