Is REISUB/REISUO to switch off/reboot safe?

I can't happen to find a fix to shutdown or reboot my Zorin OS 16.1. So far I have been using [REISUB](https://en.wikipedia.org/wiki/Magic_SysRq_key#Uses) or REISUO as a quick fix. I was wondering if it can cause harm to my laptop in the longrun if I keep using this method. For what it's worth : vim /etc/default/grub GRUB_DEFAULT=0 GRUB_TIMEOUT_STYLE=hidden GRUB_TIMEOUT=0 GRUB_DISTRIBUTOR=lsb_release -i -s 2> /dev/null || echo Debian GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" If needed I can share more details, just unsure what is needed.
