Hi @Shijun Lv ,
Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.
I understand that you would like to know if there is a way to change the default 1-minute interval for NSG Flow logs.
As of now, we do not have an option to specify the interval at which the Platform collects and updates Flow logs.
If you wish you may vote in the below forum requesting this feature. All the feedback shared in these forums are monitored and reviewed by the Microsoft engineering teams responsible for building Azure
Thanks,
Kapil
