That Processor is considered to be "OEM/TRAY" so normally it wouldn't be sold in Retail stores or online.

But one User in Europe, was able to purchase its the sister OEM Ryzen 5 2300X processor in his native country of Bulgaria according to this recent AMD Thread: https://community.amd.com/message/2908062?commentID=2908062#comment-2908062?q=ryzen%205%202500x

Plus I would contact your Motherboard's Support and open a Ticket to see if the OEM Processor, if you should be able to purchase one, will work with the your Motherboard's BIOS version.
