No.

Yes, AFAIK.

How did you try to remove or change the keybinding of TAB (\C-i, \t)?
TAB is actually an old compatible name, so you cannot use it in `bind
-r' or in double-quotes.

# remove the binding for TAB
bind -r '\C-i'
# or
bind -r '\t'

# change the binding for TAB
bind '"\C-i": "hello"'
# or
bind '"\t": "hello"'
# The following also works but is a deprecated form.
bind 'TAB: "hello"'

# You cannot use the following because it removes/changes the binding
# for the sequence `T + A + B'.
#bind -r TAB
#bind '"TAB": "hello"'
