Is it possible in Arcgis Pro to convert from Graphics to Feature
ArcGIS Pro Roadmap - July 2019 has it in the mid-term which wouldn't put it in Pro 2.5. It is definitely being worked on, but I wouldn't set the expectation that this is for 2.5.
From my knowledge, and after searching through the documentation and doing some testing on my own, the functionality of converting graphics to features in ArcGIS Pro does not yet exist. You can, however, add graphics directly to your map document via the Map Notes layer templates accessible from the Insert tab.
Based on the ArcGIS Pro Roadmap, it does look like further map graphic changes are in the works, so this might be a good thing to add to the Ideas page here on GeoNet if you'd like for it to be implemented in the future.
I believe graphics will be supported at the next major release of Pro (2.5), but this is not set in stone as per the following thread which has been on-going for 4.5 years:
Graphics and free text in ArcGIS-Pro maps!
Other posters on the thread are also looking for graphics to feature conversion capability, but this might not be included in ESRI's first release for support of graphics in Pro.
