Home Depot or most any rental yard will rent out carpet irons. I'd recommend using the right tool. It's not difficult to do. Use the lower heat setting and allow the glue to soften up slowly. We would use an awl but any sharp object, even a pair of needlenose pliers to GRADUALLY peel the tape off from one side as you slowly and gently slide the iron across the tape-------do I have to say you're doing all this from the backside of the carpet, folded back? When I've done this, usually seam repairs, I'd usually have a putty knife and scrap off wads of glue------ besides peeling the tape scrape most of the glue from the back of the goods. It's that hard thermoplastic glue that's gonna fight you from making a nice, neat tuck into the LVT as shown in the video above.
