I have a 4 wire forced air gas furnace with AC. For a wifi thermostat, do I have to use a PEK device or can I use the fan wire as the C wire?

Did some research but I can’t find anything definitive… I would be happy to give up my fan only option (never use it), would I be able to do this?

If not, can a pek device be used with any wifi thermostat, or dos it have to be specific ones?
