@José Antonio Trejo Gutiérrez Please dis-regard the answer above as the answer provided was regarding flow log retention period.
I understand you wish to know if the Flow Timeout can be increased beyond 30 mins. Currently as documented here the upper limit is 30 mins for this property. Based on our communication internally, Flow Timeout cannot be increased beyond 30 mins as this is a limitation by design.
Hope this answers your question. Please let me know if you have any additional questions.
Thank you!
