Seems to be true. https://unix.stackexchange.com/questions/591488/why-does-the-kernel-lockdown-prevent-hibernation seems to indicate it's a feature Suse developed. I have no idea if that's in the mainstream kernel by now but I guess not. If it's integrated, it'll get into Debian too at some point. If no, then it would need some dev to take an interest and integrate and test and maintain.
