Hide "Dates" Tab in Lilac

I’m looking to hide the “Dates” tab in because we don’t use it. Before Lilac, the visibility of the tab used to be controlled with the RELATIVE_DATES_FLAG.

In Lilac, it looks like the default is to have the tab enabled and I found this commit that removes the need for the flag to enable the tab. However, it looks like I can’t disable it anymore. Is there another way to disable this tab?
