Thankfully, it is a phase as long as she doesn't become habituated to this behavior - as a kind of nervous displacement behavior she resorts to in the future whenever she's bored, stressed, uncertain, etc. I'd try keeping up the different distractions and especially try to prevent her from ever starting the biting process - distract first - when you can - realize it's very hard to predict a dog's behavior but actually, once you study them for a couple of days, it's easier than you would think. A clicker could work to distract her but so can a high screech or any number of odd sounds from you, a squeaky toy(during puppyhood I almost always have one stuck in a pocket), whistles, etc. & then toss a toy or treat or anything across the floor to send her off after that thing rather than biting the carpet.
Her obedience training should include teaching her the "Leave it" command so that soon all you will have to say is "Leave it" to stop her when she's showing signs of wanting to or already begins carpet biting, then toss the toy, etc., for distraction. "Leave it" is a fun command to teach and the dogs love learning how to control their impulse for instant gratification in order to get an even better pay-off, the "Take it", along with your smiling praise and celebration with her for getting it all right - a much bigger reward in the end.
