Do we have to stop eating 10 minutes before Fajr athaan for fasting?

So the most important part is that you stop eating before the start of Fajr. So let's say for example Fajr starts at quarter to five, 4.45, you must stop eating before the clock tends to 4.45. Now the sunnah of the Prophet sallallahu alayhi wa sallam was actually to stop eating a little bit earlier. So you can stop eating a few minutes earlier and then use that time before Fajr starts because it's the last third of the night to make dua. And that's also fine. But the key thing is you must stop eating before the start of Fajr. You can eat all the way up to the start of Fajr if you want, but don't eat once Fajr has started.
