Unfortunately, no. You will need to perform the above-listed steps on a web browser. The Netflix app doesn't have the same functions as your account settings on a web browser. If you don't have a computer handy, use your smartphone's web browser to access the Desktop Site. For example, if you're using the Chrome app, open Netflix, tap on the three-dot icon in the upper right, and tap the Desktop site box. The page will refresh, and you can access the log-out options as we did above.
