Just to let you (and possibly others) know that the new BF1 update (Turning Tides, 30th of Jan) + yesterday's (29th of Jan) NVidia driver update fixed the issue on fullscreen. I switched to fullscreen and the usual option of "1920x1080 60Hz" had reappeared (previously only 59.94 could be selected) and now fullscreen works as it did before.
Some have also reported that at least on HDTVs the Fall Creator's Update forces the color output to 12bpc regardless if the TV supports it. I don't know if that affects monitors too, but if someone gets this issue it could be a thing to try. From NVidia Control Panel's resolution settings, use NVidia settings and force it to 8bpc.
