Short answer: yes, it can get close to your Dell, but only if you pick the right switch on purpose — a regular clicky board definitely won't.

For night use in a small house I'd skip anything clicky and look for a board with silent linear or silent tactile switches. Those have little dampeners built in, so you don't get that sharp clack on the way down or back up. A normal tactile like a Brown is quieter than a Blue, but in a quiet room at night it can still sound pretty present, especially on the bigger keys.

The other thing that surprised me when I first switched was how much of the noise is just bottoming out — smacking the key all the way down. A slightly heavier switch, a desk mat underneath, and just easing off a bit made more difference for me than chasing a specific brand.

If you can, try a couple of switch testers or a display board in a shop first. Your Dell is a good baseline: if the board you try sounds about the same or softer than that in a quiet room, you're probably fine for late-night use.
