Was asked before but were no answers, maybe more luck this time.
So, Selim Yavuz does not conquer Mamluks in 1517 and is unable to wage war with Ismail I. of Persia, for any number of reasons you like ( total defeat in Battle of Chaldiran and decides to stop there, civil war, 100% war effort thrown at Hungary and Austria ...). That gives the time for Persia to stabilize, neutralize Shabayanids ( Uzbeks ) as they did IRL and then turn towards Egypt.
What do you think of the regions fate in this scenario ?
