Is Intel Rapid Start still available on modern ThinkPads?

I've been trying to test Intel Rapid Start Technology on my X1C9 and see how it compares to os-driven hibernation.

But my firmware doesn't show the option for IRST. I've seen screenshots from other people having this in the Power section.

Is this even a thing on recent ThinkPads? Has anyone been able to enable it?

I have the partition with correct GUID type. I also have OPAL enabled on the drive, but I don't think it should affect this feature... or does it?
