Preflight/Options HTTP call in rest api from custom plugin

Summary:

We have a custom plugin and are making multiple REST API calls to OFSC to fetch and update data. We can see in the browser's network tab that for all fetch api calls, an options (preflight) HTTP call is made before the actual get call is made.

Is there a way to cache this options call, so that it is not repeated?

Is there a way to stop the options call altogether?

Thanks,

Rajesh
