Disabling Secure Boot on a Home Computer running Linux

How likely is it that disabling Secure Boot on a home computer running Linux would suffer from the advertised threat of > unauthorized code—such as bootkits and rootkits—from being executed > during the boot process? How would such animals get onto a home computer of which I am the only user? It seems unlikely to me that that would be a problem in my instance. **But maybe I am missing something?** I am interested in doing this because I would like to enable hibernation on this computer, which, because it has an nVidia GPU, cannot be reliably suspended. The computer has a swap partition and nvram rather than a hard disk, and I think the delays would be tolerable and less annoying than the frequent need to reboot.
