If the business don't see the value of those things, you're more likely to convince them if you can prove how those things can actually save/make money.

Some pointed out things like retrospective on outages, but there are other things, like how testing could reduce the number of bugs, thus, reducing context switching and debugging times.

You could even tight it directly to money by measuring what a bug cost and make a experiment in a team showing testing reducing that cost over time.
