I'm not familiar with your setup and just a little familiar with my own but I have a "Beacon" with Digifarm and an Intergra with AgLeader's Ontrack 3 (I believe( and when it was all set up originally I paid a subscription to Digifarm for the RTK and had a tablet that had the Ntrip app on it and was connected to my cell service.  Everything worked great but I had to pay approx. $700+ each year.  I signed up for Indiana CORS and I  believe I had to give the Beacon a different IP address or something like that and maybe the Ntrip app also, and use Indiana's CORS system for no charge.  It works great and is free.  I can't, off the top of my head remember what all I had to do but it wasn't difficult.  I may have to redo it all as I need a new Verizon tablet and it will have to be set up.  So if I do fairly soon, I'll post what all I had to do.

   I'm sure someone on here is very knowledgeable about all of this and can tell you exactly what to do.  Just wanted to let you know that I think what you want to do is most likely very possible with your equipment also.
