Un-Route a Net Interactively: Use the interactive un-route tool. This allows you to click and drag to remove routing along a selected net. This command can be accessed through Route > Un-Route > Un-Route.

Un-Route an Entire Net: You can un-route an entire net by selecting the net and using the interactive un-route tool to remove all traces of that net. Another method is to find the net in the PCB panel and perform an un-route function via right-click.
