N. ACM-approved university I'm aware of would offer a 4 year degree in CS/IS based just on VFP; it's impossible to teach certain basic courses like data structures and algoithms, or a number of more advanced topics, based on the use of VFP. You couldn't get an adequate education in CS from that perspective.

You can take the certification exams for VFP, but that's not the equivalent of an undergraduate degree in CS.

I seriously doubt you'll find graduate and post-graduate courses based on VFP. I'd look into various undergraduate programs with a course in database design and theory, but in most cases, these will have prerequisites like basic algorithms and data structures which will require the use and mastery of a language like C or Pascal - harnessing concepts like trees, linked lists, digraphs, sorting and searching and the like require languages supporting detailed low-level structures. Most of the courses I taught had prerequisites involving C++ or LISP.
