Adobe Analytics API 2.0: What is the equivalent endpoint for ReportSuite.SaveEvars from v1.4?

I'm migrating from Adobe Analytics API v1.4 to v2.0 and need help finding the equivalent endpoint for ReportSuite.SaveEvars.

Current Implementation (v1.4):

1. Using ReportSuite.SaveEvars endpoint
2. Part of the Report Suite API

Issue:

1. In v2.0's Swagger documentation, I cannot find the Report Suite API.
2. While there is a Report Suite API mentioned in the v2.0 endpoint guide, it only contains GET methods - no PUT, POST, or PATCH endpoints are available.

Question: What is the equivalent endpoint in Adobe Analytics API 2.0 for saving eVars that replaces the v1.4 ReportSuite.SaveEvars functionality?

What I've Tried:

1. Checked the v2.0 Swagger documentation
2. Reviewed the endpoint guide for Report Suite API in v2.0
3. Unable to find any equivalent write operations for eVars
