Update Agreement Lines using Excel VBCS

Summary:

We have a need to remove data from a Flexfield that is on the BPA line for several BPA’s. I have reviewed and tried to use the REST Endpoints that are provided but I am not having any luck. Is there any way to remove data using VBCS on agreement lines? If yes, what REST Endpoint will allow us to remove the data. If not, is there another way?
