How to remove channels w/o rescanning

Now that we have the updated version I am getting unwanted channels on my live list. How can I remove those without having to rescan?

which gen 4 app.

Roku ultra

Settings → Guide → Channel Lineup.
Do NOT rescan channels.
Move to the list of channels and select or deselect whatever channels you want.
Save and continue and it will update the guide.
