You can't really do this with just the Browse tab, but this would be somewhat antithetical to the purpose of the Browse functionality, which is more of an additive operation (e.g. "show me all of the images that are NEFs OR images that were taken in 2024). Have you tried the Filter tab instead (which would be something more like "show me all of the images that are NEFs that were taken in 2024)
I've attached a screenshot of how to set up the filter. You can click the snapshot menu (the little flashbulb icon) to save your filter so that it is easy to pull up again in the future. You can select multiple lines in a Filter by holding the Command key on your keyboard while clicking on the line.
