Is "view list" something that only exists on a twitch server? Or are you referring to the nicklist that appears on the right side of a channel window?
If it's the side nicklist, I'm not aware of a way to delete it, though you can make it not be visible by setting the nick to same color as the background, by putting this in nicklist tab of popups:
hide $$1:cline $color(listbox) # $nick(#,$1)
show $$1:cline $color(listtext) # $nick(#,$1)
