How do I patch my DSDT?

So, I got macos ventura installed on my acer aspire 5 like 2 days ago. Ive been ironing out the small kinks so far. But, theres one thing that ive been stuck on, editing the dsdt. I have been looking to fix my brightness keys (the slider works but the keys dont) so i came across this post (https://www.insanelymac.com/forum/topic/305030-guide-how-to-fix-brightness-hotkeys-in-dsdt-ssdt-hotpatch/) and ive been stuck at step 4. I applied the patches and all, but i have no way to save/upload the modified dsdt onto my system. Any help is appreciated.
