I did find both of those settings, and they go up to 10 and 5 seconds, respectively. Which is better than nothing, I guess.
As for the rest of your reply - wow - it's impressively condescending. Nice work. 🙂 For the record, I've been programming professionally for over 30 years (professionally, meaning getting paid), and know over a dozen languages (Rust being the latest - my Rust code does still have compiler-errors, and probably will for some time).
Writing flawless code is totally irrelevant, in this case - I'm doing this video/course (GodotInventoryUI), and have a video playing in one screen, and the editor in another screen, and actually type the code I see/remember in the editor, as the video goes on. This sometimes takes more than 10 seconds, and I find it irritating to see the entire line flashing red as a result of it.
