Shifting hours and flexibility of IF

I tried IF last year by skipping dinner. But my family always eats and became impossible to avoid eating. I'm from South America, and here dinner is usually after 9PM, in my home we usually ate dinner around 10 PM or so. I wanna give it a go again. My idea is eating my last meal (dinner) around 10 PM or so. And eating lunch at 2 PM (this is basically my schedule tho). But here's the thing, I've read so many mixed opinions on what meal to skip, etc. I'm just wanna have some input on that kind of schedule. Also, the other question is about flexibility. If some night my dinner is delayed and I eat at, idk, 11 PM. Does just doing the 14 hours of fasting window works even if you delay it an hour? Thanks in advance, I've read A LOT of post here, but those questions remained so I decided to post.
