modern experience – Dynamic filtering with Gallery list view in SharePoint Online

I have found a way to implement a substitute for a tab control in SharePoint Online. In SharePoint On Premise I used Hillbilly Tabs, but I am not allowed to use SPFx at our tenant so I had to look for other solutions.

I use two lists, one list contains the items that used to be visible on the tabs and then I use that list to perform dynamic filtering of the other list.
In the view settings for the first list I unchecked "Allow individual item checkboxes", because in a tab control you only want to select one tab at a time.

This setup works pretty well, but the user experience is of course a bit odd. So I was happy to find the "Gallery" list view. I now have the chance to line up the “tabs” horizontally.
But when I switched to Gallery view, the item checkboxes showed up again (even though "Allow individual item checkboxes" was still unchecked in the view settings).

And when I click an item in the list, to filter the other list, no filtering is taking place. Instead I am redirected to another place.

This is how the auto-generated code for the gallery list looks like. Is there anything I can change in the JSON to keep the good behavior (with filtering functioning and no checkboxes) of the basic list I had?
