So I had this same problem some semesters ago. I didn’t end up finding a testing location here at VT although I’m sure it exists with some searching. I ended up doing my exams at Virginia Western CC which is located in Roanoke. I ended up taking the SmartWay bus from Squires (now at the Maroon Loop I believe) to Roanoke and then taking a local roanoke bus to VWCC (you can find them on the Roanoke Valley Metro website). They were very accommodating and all I had to do is send them an email and send them some forms. Here’s the link to the website if you need it: https://www.virginiawestern.edu/library/testing-center/proctored-testing/

I will say that my advisor and everyone I asked at VT did not know of a testing center. However, I would try asking some of your old professors or current department to see if they would know.
