Is there a way to generate unique random number using rand and randn in Simevents?

Question

Is there a way to generate unique random number using rand and randn in Simevents? I need to generate random numbers for entity service time using rand and randn, but it seems like the numbers generated are repeated. I have tried using rng('shuffle') and rng using algorithms (like rng(1,'philox')) by putting the codes in every servers I have. However, the numbers generated are the same. I have also tried this: https://www.mathworks.com/matlabcentral/answers/334395-how-to-create-random-seed-to-have-different-results-at-each-simevents-run Is there a way to generate unique random numbers using rand and randn in Simevents?
