Is there a config entry for the "Show hidden objects" checkbox in the local directory browser?

If I navigate to my local home directory by entering “file:///home//” into the url bar, then firefox (v145) shows a kind of directory / file browser. (Interestingly, I can find no documentation about this internal file browser anywhere!)

On the top right-hand side there is a checkbox entitled “Show hidden objects”. Is there a config option or any other programmatic way to set the state of this checkbox?
