Conflict Resolution Behavior Onedrive Rest API

Hi,

Does anyone know how to make a request for uploading a small file (<250MB) with a cusotmized conflict behavior?

In the article, it mentioned:

I seems that it's feasible to make such a request with customerized conflict resolution behavior.

Actually i am using graph sdk to make my life easier. If someone can provide sdk code example to achive the request, it would be even better, thanks.
