Jeffrey, do you have a link explaining it with more details? I expected
some kind of cooperation of machine firmware and systemd in respect to
power management.
No, sorry. It is based on my experience using SSH to access machines remotely. Or more correctly, not being able to SSH into a machine that went to sleep.
I assumed that disabling power states in UEFI setup may make them
unavailable for OS.
