Or you can cut it with a Stanley knife. Cap it with a push in plug or a Sharkbite cap.

Try to cut it off right at a junction. If there is a 15' run of pipe to a dead end one of two things will happen: - The antifreeze won't reach much of the pipe. - If you do get antifreeze in, it will slowly leech out all season long flavoring the water.

Best way would be remove the “T” that feeds the hookup and replace with a straight coupling.

The next owner or even yourself might be appreciative of having the plumbing in place when they next need it.
