This is expected, because NVDA provides its own touch screenn support gestures so blind people can use it. Closing as INVALID.

The scrolling works with the stylus, but not with finger on the Surface Pro 4. Are there any STR you can suggest to enable touch screen support gestures that we might be missing?

Finger scrolling doesn't work with NVDA on Acer Aspire SW3-013 either.

As noted by Marco in comment 1:

It's not possible for a blind user to use normal touch screen gestures, since tapping the screen would activate items without the user being able to inspect them. Thus, NVDA "takes over" the touch screen and provides its own gestures. This is expected behaviour and there is currently no way to override it.

See comment #1 and comment #4 why this was closed as invalid.
