Make section border/separator invisible in list form body custom layout with JSON

Question

I have a form section that has 4 fields to it, but we would prefer to have these 4 fields organized in 2 rows and 2 columns, rather than to flex, which ends up as 1 row with 4 columns.

A simple work around was to split the section into 2, with the second having a blank title. However there is still a separator (horizontal line) between the 2 of them, is there a way to get rid of this or make it invisible? Or perhaps some other way to accomplish this?

Here's an image that might explain it better:

Unfortunately, removing separator/line is not possible using JSON formatting capabilities.

Unlike the header and the footer, body configuration only allows defining one or more sections and adding one or more columns into each of those sections.

Body configuration does not support advance JSON customizations like header/footer (or column/view formatting in list views).
