How can I enable it from where I’m at?

Fortunately, someone () wrote a really nice guide on that:

[Tip] Enable Magic SysRq Key (REISUB)

The Linux kernel authors have provided a very nice feature of issuing low-level commands to the kernel directly, regardless of the state the system is in. This is called the “Magic SysRq Key”, because these commands are issued by pressing the SysRq key on the keyboard (if you can’t find it, typically, it shares the same physical key as the Print Screen key, but on some laptops it can be elsewhere). A common use is to reboot when the computer freezes and becomes unresponsive due to some software…

If your computer is frozen and you can’t do anything, and you have not enabled the magic SysRq key, you’ll have to hard reset it, there’s no way around that, unfortunately. Keep your fingers crossed.

If you can’t get to a desktop, either boot to a TTY or chroot from an ISO image so that you can enable the magic SysRq key.
