Either USB port can be used to flash the firmware with WCHISPTool (Windows only) and programming can be done in MounRiver Studio IDE that is said to be similar to the Arm Keil MDK, and available for both Windows and Linux, which is said to include a download tool too (So WCHISPTool may not be necessary?). You’ll also find the CH32V307VCT6 datasheet and reference manual, as well as code samples on Github. That repository is for the WCH board.
