Lan Cable and Usb tethering

[Chaqui]

Is it possible to use lan cable for browsing, downloading or other something that consumes high data and usb tethering (from phone) for gaming? I have seen an app from ROG laptops that they have this software (gamefirst or gamefast) to have separate connections for browsing and gaming. Is there any third party app or anything you could suggest?
