The reason is that Dell replaced S3 sleep with Modern Standby.
Modern standby is turning on my XPS so much it can actually get dangerously hot in my backpack.

It's a knowledgebase article using a standard Support/Resolution template (that might not be changeable). The irony is thoroughly amusing and IMO appropriate.
I recommend the powercfg command line approach instead of the UI.
TLDR: "enables the system to stay connected to the network while in a low power mode" [...] "with the added benefit of allowing value-added software activities to run periodically" [...] "When a system service or background task requires network access, Windows automatically transitions the networking device to an active mode" [...] "longer active intervals occur for a variety of reasons, for example, processing incoming email or downloading critical Windows updates."

Don't you have a way to disable it and go back to what Microsoft calls Traditional Sleep?
Yes, on some laptops, such as Lenovo, you can switch from "Windows" to "Linux" sleep mode in BIOS (yes, they are really named after the OS).
Here's the rub: you have to reinstall Windows. There used to be registry edit you could do but that seems to no longer work. At least it didn't for me.
No OP, but most of Dell's current lineup no longer has support for any other modes in the firmware. So no, I can't disable it.
So often what happens is nothing: the battery often drains completely overnight and it's guaranteed to be dead on Monday morning if I let it "sleep" on Friday.
