Hard to say yes or no here. Language is not precise enough.

You ask initially about adding a peripherial but your DTS overlay only works for parametrising (changing) an existing peripherial defined in board or SOC device tree.

Note that you can define your own peripherial in the DTS overlay, but syntax is different of course.

Using your own peripherial can also require a DTS binding if there is no zephyr (or nordic) driver or if the driver does not exactly do what you wanted it to do.

Writing a procedure that covers all of these cases will be rather hard.

Note that vs code build config can currently break if you had DTS syntax errors. I recommend using west build command line tool as workaround.

Nitpick: A ton of (modern-ish) drivers auto enable if they find a compatible DTS entry, so you usually don't have to enable them in prj.conf manually.
